Spring is fast approaching.
I can tell from the daffodils and crocuses coming up in the yard.
The seed catalogs piling up in the mail box.
And a note on my wife’s calendar saying simply, “chit”. Continue reading Post G23-002: That potato isn’t going to chit himself.
To get to the punchline, yep, as of right now, that’s how it looks. It will all make sense by the time you get through this. Continue reading Post #1699: Is “dry your blade” really all about water spots?
This post replaces all my prior posts on extending the life of a razor blade. Because, I think I goofed.
Based on my most recent analysis:
Whatever it is that dulls a razor blade, short of abuse that puts big nicks in the blade, you can’t see it under a low-magnification microscope. Blades that appear perfectly sharp, and (by measurement) retain their full width, can, nevertheless, be too dull to remove your beard. I have no idea why.
The ONLY test for whether a razor blade remains sharp and usable is to shave with it. Neither examining it with a low-power (USB) microscope, nor testing it with a home-made sharpness tester, provided useful information on how well a blade would shave.
Of the three things commonly cited on the internet, for extending the life of a razor blade, I now believe that:
Number 2 is a change from my prior posts, and that’s really the key point of this post.
Edit: And I now know why: Water spots. A calcium carbonate deposit (a.k.a., water spot) is much thicker than the edge of a razor. Tested and confirmed by comparing distilled water to tap water, Post #1699.
The upshot is, if you use shaving cream or (arguably) a high-end shaving soap, and dry your blade after each use, you’ve done your due diligence to get the most out of your razor blade or disposable shaver. Whether more extreme measures add to that — keeping the blade stored in oil, freezing it, or whatnot — would require more analysis.
A recap and a bit of detail follows.
I’m trying to determine whether any of the suggestions for extending blade life, commonly found on the internet, actually work.
I boiled this down to:
I wanted to be as objective as possible, so I tried to avoid rating blades based on how the shave felt, figuring, there’s a lot of subjective leeway in that. Instead, I was going to rely on how the looked, and how sharp they appeared to be, based on a home-made sharpness tester.
In hindsight, that was a mistake. Appearance was an adequate way to judge blades if they were thoroughly abused. But for blades that have not been abused — without visible nicks or erosion in the edge — it turns out that a sharp, usable blade looks just like a dull, unusable one.
If nothing else, this razor blade test has broken me of a life-long bad shaving habit. I shave(d) with soap. Most recently I’ve been using Dove, because that’s supposed to have more emollients in it and be generally nicer to your skin.
And, not unrelated, I’d typically get three shaves out of a blade before I got the urge to replace it. Maybe five, at the outside. But by the time I got through that fifth shave, it required multiple passes of the blade and, basically, it hurt.
For this final test, I decided to shave half my face using Dove soap, and half with Barbasol. The main active ingredient in Barbasol is stearic acid. That’s the same as the main fat in coconut oil, and it is frequently recommended as a beard softening agent.
From the first shave, it was absolutely clear that shaving with Barbasol was a lot better than shaving with soap. In the end, I got ten decent shaves with Barbasol, versus a typical 3 to 5 shaves with soap.
That one is case closed, as far as I’m concerned. I’d conservatively say that using Barbasol easily doubles blade life, relative to shaving with Dove soap.
If you want a more in-depth dive into the ingredients of shaving cream and shaving soap, see Post #1668.
Stropping means running the blade “backward” — opposite the direction of cutting — over some suitable material. The idea is to polish and hone the very final edge of the razor’s edge.
The practice of stropping razor blades to re-sharpen them disappeared just about the same time that stainless steel blades (above) took over the market. I strongly suspect that this was cause-and-effect. Stainless razor blades are just too hard (or wear resistant, take your pick) for stropping to have much effect. I went through this in the historical perspective on stropping, Post #1689.
I have now tried all of the following, and none of it resulted in restoring a dull blade to usable status. I.e., from the standpoint of shaving, none of this sharpened a stainless steel blade:
None of that seemed to make the least bit of difference in how well the blade shaved. In particular, using an actual commercial leather strop and compound, 30 strops, did nothing to restore a blade to usability.
Finally, literally sharpening a blade — removing significant amounts of material from the blade edge — destroys its usability. It makes it too narrow for the safety razor, and it then leaves stubble instead of cutting cleanly.
Stropping, steeling, sharpening, and so on. Total bust.
For this one, I cooked up a fairly elaborate experiment to show that nothing happened to stainless steel blades if you leave them wet. I took six blades (three new, three used), kept one edge wet for a week (either continuously, or dunked in water once a day), and kept the other edge dry.
And, by eye, there was absolutely no difference, under a low-powered microscope, between the wet and dry edges. There was no difference in sharpness, based on my crude sharpness tester. So I originally concluded that drying a stainless blade after every use is unnecessary.
Then the stropping experiment finally ended, I put a different razor blade in my razor. This was one of my test blades above, and I expected it to shave like a new blade.
Well, I was half right. One side shave just like a new blade. The other side was so dull as to be unusable.
When I pulled it out of the razor, the unusable side was the one that had been dipped in water a few times a day, for a week, and left to dry at room temperature.
So, I’ll be damned. I can think of no other explanation for this, other than, failing to dry off that blade, for what amounts to a couple of week’s worth of dunking, left it dull.
I may look a little more carefully at this. I want to repeat that. And some people say that extreme measures can preserve blade life even further. Others claim that the dulling is due to build-up of minerals on the blade, from hard water. So I may want to look at all of that.
But as of right now, for reasons that I absolutely cannot fathom, it appears that you do, in fact, need to dry off a stainless blade to keep a sharp edge on it. Or, at least, failing to do that will dull the edge.
I have no clue why that is. I’m only attesting that, based on a sample of one blind shave with one carefully-treated blade, that appears to be true.
Anyway, dry off your stainless steel blade. Apparently confirmed.
Edit: See next post for the explanation. It has nothing to do with rust or oxidation of a stainless-steel blade. Post #1699.
Marriage. Crap. Pile o’ shit. Ex-furniture. Late mid-century-modern TV chair.
This thing, or, more properly, these things:
This is what’s left of two American-made, walnut, totally “moderne” TV chairs, likely dating to around 1970. There are famous and expensive examples of this type of furniture. But I suspect this was “Sears Better” from the period.
The back story is that I moved into a little 1950s house in Vienna VA in 1993. The sole criterion was that I could walk to the Metro, as my job was in downtown DC.
Across the street was a nice couple, him retired military, her his wife. Colonel Pike was a force to be reckoned with. After a snowstorm, I’ve never seen a sidewalk shoveled with such precision. I can still recall what must have been this 80-year-old guy, walking around on the roof of his house, fixing this and that. Adjusting the weather vane in the shape of a golfer.
As a guy, I occasionally did roof maintenance myself. But, at that age, tromping around on his roof? Simultaneously macho, admirable, and batshit crazy. It gave me the willies watching him. I don’t doubt that at 80 he was more than my roof-top equal at the time. Yet I cannot even guess how his wife felt about this.
As time wore on, I got in the habit of shoveling our neighbor’s sidewalk as I shoveled my own. Including Colonel Pike’s. No doubt, not to his standards, but you do what you can.
Eventually, cancer got him. I believe it was leukemia. I clearly recall him saying that. So no doubt he faced up to it.
My wife caught up with Mrs. Pike, at some point, just kind of sobbing while standing on the sidewalk. My wife did what she could. I cannot imagine the depth of that love. Lost without her life-long partner.
But let’s put that aside, guy-style.
The point here is the mounds of possessions that got taken to the street, as Mrs. Pike planned to move to Texas, to live near her daughter.
That was Döstädning. Swedish death cleaning. Though I did not know the term at the time.
My son, with an eye for treasure, picked these two chairs off the pile. We used them for years, but 40-year-old fabric and foam just didn’t stand up to a bunch of kids crawling all over them. In the end, the foam broke down, the fabric ripped, my son made one valiant attempt to de-construct what was left.
And what you see above is the result.
Now I’m retired, with way too much time on my hands. I’m going to try to put these back together. Not exactly as they were before. But in the same spirit, as “TV loungers”, or whatever.
We’ll see how it goes.
They say that retirees need hobbies to keep them busy. As a former small-business owner, all I can say is, screw that. I’m just not motivated to turn my time and treasure into low-valued objects.
But reconstructing an interesting artifact from the past? Yeah, I guess I can get on board with that. So here goes. Furniture Restoration 101.
When the recent manufactured controversy over the Microsoft Xbox hit the papers, it resonated with me.
Probably 15 years ago, we bought a gaming console for our kids. (For the kids, of course, because we adults would never consider wasting time playing video games.)
We bought a Nintendo Wii. Not due to the quality of the gaming, but because the Wii console used about one-fifth the energy of the Xbox and similar alternatives. (Ask me what screen I finally got to on Wii Tanks.) The Wii had a lot of other interesting features — not the least of which was the Mii parade above. But the main reason I picked it was that it had a vastly lower carbon footprint than the alternatives at the time.
At the time, the characterization of Xbox energy use was that leaving an Xbox running was like leaving your fridge door wide open. It literally used as much power as the typical American fridge.
That does not appear to have changed in the past couple of decades. Exactly how much energy a gaming console uses depends on what you’re doing. But it’s clear that running a graphics-intensive game, on an Xbox, and using some modest-sized display, could easily consume 300 watts.
Here’s a site with a nice table showing typical ranges of energy consumption for home gaming consoles. In particular, they have a nice table for the PS4, showing that the difference between letting the machine run, unused, and putting it on standby, is about 85 watts. That matches my recollection for the Xbox.
And, doing just the tiniest bit of math, if you let that game console run at idle all the time (i.e., showing the menu), that will cost you about 750 KWH per year, compared to powering it down to standby mode. That 750 KWH is, in fact, more than the average U.S. fridge, per year.
The upshot is that, as I recalled, if you don’t enforce turning your Xbox off, but instead just leave it idling, the additional electricity cost is more than the cost of running a refrigerator.
As is typical with modern news-righteousness, everybody seems to start yelling before you can get a clear picture of what just happened.
If you want a clear explanation, start here.
At issue is the difference between Sleep mode (with instant-on), and Shutdown mode (where it takes about 15 seconds for the Xbox to reboot). Just as with your laptop, one of those keeps everything in memory, keeps memory warm, and uses more power. The other one writes things off to storage, then more-or-less turns the machine off.
Sleep consumes perhaps 15 watts, while shutdown mode consumes just 0.5 watts. Which doesn’t sound like much, but for an Xbox continuously plugged in, the 15 watt Sleep mode consumes about 130 KWH per year more than the 0.5 watt Shutdown mode.
Just FYI, that’s enough electricity to power my wife’s Prius Prime for about 750 city miles of driving. At the prices I pay in Virginia, that’s about $15 worth of electricity per year.
In the past, Sleep was the default mode. But starting in March 2022, Microsoft change the default to Shutdown, rather than Sleep, for newly-manufactured units. So, to be clear, this new default has been in place for almost a year, on newly-purchased units.
The current controversy arose because Microsoft is updating the software on older Xbox units to make them match the standard that has been in place for about a year, for new units. That is, they are going to make Shutdown the default.
Users can override that if they wish.
I don’t know how the party of Teddy Roosevelt ended up being the pro-energy-consumption party. But that seems to characterize the Republican party today. Coal is good. Renewables are bad. Energy use is good. Energy conservation is bad.
At root, this is a controversy about a manufacturer choosing to make the software on older gaming consoles match the software that it has put on consoles manufactured for the past year. Mainly, this changed the default “off” setting from Sleep to Shutdown, which I calculate should save about 130 KWH per year per unit.
Near as I can tell, Microsoft updates the software on my computer any damn time it pleases. And I actually depend on the computer to get along in the real world. How on earth this update to gaming-console software became such a cause célèbre among the Right, I cannot even begin to fathom.
But, ultimately, I think it’s a good sign. If that’s the biggest thing they have to complain about, then things must be going pretty well.

I’m going to continue to check in on the rate of newly diagnosed COVID-19 cases, from time to time. It’s unchanged from a couple of weeks ago, at 15 new cases per 100K population per day.
Per the CDC, we’re seeing about 550 COVID-19 deaths per day, and about 4500 COVID-19 hospitalizations per day. The deaths number is up quite a bit from a few months ago, but winter is hard on the frail elderly. My take on it is that COVID now sits alongside various forms of pneumonia as a common terminal illness for the oldest old.
The only other thing of note is that there’s a lot of variation across the states. A lot of the Rocky Mountain states are in the neighborhood of 5 /100K / day, a lot of the East Coast is still around 20 / 100K / day. No idea if that’s real or just variation in propensity to test.
I have rebased my graphs to being with 1/1/2023.

OK, I lied. My last post was not my final post on shaving.
To complete the analysis of factors affecting razor blades, I need to document normal variation in beards. In short: It’s huge. All other things equal, that almost certainly leads to huge variation in razor blade life.
This scholarly article will probably tell you more than you ever wanted to know about beard hair. A key sentence is:
The density of beard hair follicles varies with facial area and ethnicity. Values range between 20 and 80 follicles/cm2
I interpret that to mean that, within normal variation, some guys have four times as many beard hairs (per skin area) as others. All other things equal, that’s going to generate four-fold variation in razor blade longevity.
There is further variation in hair thickness, stiffness, shape, and so on.
With that much background variation, there really is no such thing as normal razor blade life. There’s only what’s normal for you, and what you can plausibly do to extend it.
The only shaving technique studied in that article is wetting (hydrating) your beard. Which I think anybody who shaves with a blade understands to some degree.
The force needed to cut a beard hair is reduced by about 20% within the first minute of water contact. After four minutes, the cutting force is reduced by 40% and does not significantly decrease further with longer hydration
This correlates well with the standard advice you’ll hear from shaving experts, which is to let your shaving soap or cream sit on your face for a minute or two before you shave. (Both shave cream and soap lather contain water.)
Interestingly, I can find zero scholarly evidence that the fat (e.g., stearic acid) in shaving cream does anything to soften hair. And yet, I have found that shaving cream extends blade life, compared to shaving with soap, even though both methods result in hydrating the beard prior to shaving. Moreover, so far (shave #10 on the same blade, today) it extends blade life far beyond what you might expect from the 40% reduction in cutting force cited above. And, all major brands of shaving cream or gel contain one of two fatty acids as their main component.
Maybe that’s strictly a skin softener? Maybe a lot of the wear-and-tear of shaving comes from the skin, and not the hair?
Beats me. Whatever the underlying mechanism is, it seems to work. And every manufacturer of shaving cream seems to include it as the main ingredient after water.
I guess, now, I really will call it a day on posts about shaving.
That’s not to say that I’ve exhausted the topic.
It’s more than I’ve exhausted my willingness to track down all the nutty claims that are made about shaving and razor blades. Every time I look, I find another one. Today, it’s a patent claiming that dipping razor blades in 12% to 20% citric acid will extend their life at least five-fold, by preventing the formation of “mineral crystal buildup”.
Edit: Well, as it turns out, upon further research, that’s not so nutty after all. See Post #1699 on how water spots (calcium carbonate deposits, or “mineral crystal buildup”) can coat the razor edge and so dull the blade.
Let us never forget that you can keep your blades sharp forever by keeping them in a pyramid-shaped object. But only if you orient it exactly with the earth’s magnetic field. And yeah, there’s a patent for that one, too.
Edit: Nope. See below. Honing a worn stainless-steel blade with a knife steel made the edges look a lot better. But the blade still shaves badly. And I have no idea why.
I think I’ve figured out a possibly-effective way to strop or hone a stainless steel razor blade. Possibly. Use a sharpening steel. The thing pictured at the top of the post.
Don’t use an abrasive (e.g., diamond) steel. Use a common carbon-steel knife sharpening rod. The last post demonstrated that you can’t abrade much off the edge before the blade is ruined for shaving.
Use the “pull” technique. Weirdly enough, half the experts on Youtube pull the blade across the steel. Half push the blade, as if you were cutting into the steel. That suggests to me that this works either way. And pulling a razor blade is going to be a lot easier. Like this technique (Youtube link).
Hold the blade at very shallow angle to the knife steel. Start at one side of the edge, and pull it across and up the steel. Flip and repeat as often as you want, because, based no seemingly expert authority, it’s almost impossible to over-steel a knife edge.
I’m not entirely sure this works, but it’s the best I’ve come up with, and it seems to do something.
For sure, this does nothing for any chips in the blade edge that are large enough to be visible with a microscope. So if a blade edge is badly eroded, honing it in this fashion isn’t going to fix it. But, that’s fair, as honing or stropping isn’t supposed to repair a damaged cutting edge. Those really just clean up the very final finish on an otherwise sound cutting edge.
But, maybe it does something to the very edge of the blade. After vigorous stropping in this fashion, the stropped edge of a razor blade feels sharper when run across the ball of the finger. So much so that I can tell one edge from the other in a blind test.
Unfortunately, I have no other evidence that this is actually doing anything. Whatever is happening at the very knife-edge of the steel is far too small for me to see with my crude microscope. My home-made sharpness tester had too high a variance to tell me much. And, with one blind shave test, I can’t really feel any difference in shaving.
Edit: Finally, after 11 shaves with one Personna blade and Barbasol, I judged the shave to be inadequate. Here’s a contrast of the worn blade and a new blade, after that 11th shave. You can clearly see that the new edge is perfectly straight, but that the worn edge has quite a ragged appearance.
(Parenthetically, you can see what a difference shaving cream makes relative to Dove soap. Unlike my used blades after soap shaving, on this blade there are no huge nicks in the edge, just an uneven razor edge.)
This amount of edge wear is enough to cause me to change to a fresh blade.
I did my best to see whether or not the blade was any narrower, per my prior experiment in sharpening a blade. As far as I tell, it’s not. So I’m not wearing out the blade by making it too small to give a good shave. (If that were true, there would be no point in proceeding, because I can’t restore the blade to its original width.) I’m wearing out the blade by giving it a ragged razor edge.
So, what the heck. I carefully steeled/honed that worn blade. Held the blade in my hand, and gave it about ten strokes across the steel, on each edge, flipping the blade with each stroke.
Below you see two views of the same pair of blades after passing the worn blade over the knife steel. By eye, the worn edge now appears somewhat less ragged. Not perfect, but significantly straighter. Which, I think, is roughly what a knife steel ought to do. Clean up the very tip of the razor edge of the blade.
I still don’t know if this improved the blade enough that it can still used. But I’m going to try shaving with it tomorrow. (Honestly, it’s hard even to be sure that I’m not kidding myself about the steeled edge being straighter.) Shaving is clearly going to be a subjective test, and if I’d thought about it, I’d have steeled just one edge, so I could do a blind shave test of one edge versus the other. But that’s water over the dam at this point.
I’ll re-edit this one more time, after I’ve shaved with the worn-and-carefully-steeled blade.
Final edit: Still doesn’t shave worth a damn. I have no idea why.
The blade remains the correct width. I pulled out a micrometer, and the worn blade is exactly the same edge-to-edge width as a new blade (to within the 0.01 mm resolution of the tool.)
The blade edge looks good. Under magnification (with a cheap USB microscope), the blade edge is nice and straight. I’m hard pressed to tell the used blade from a new blade.
The upshot is that I have no clue why the blade won’t shave. Possibly the blade wear goes on at a scale that I just can’t see with my current level of magnification? I hate to leave it like that, but I can’t see any reason why this blade no longer shaves well. But it doesn’t.
That said, this brings my razor blade deep-dive to closure. The final question was whether or not there was anything you could do to re-sharpen a stainless-steel blade. Edit: My answer is, yeah, maybe. Try using a knife steel. As of this writing, my answer is no. As with stropping on leather, I can use a knife steel to clean up the edge, but I can’t make the blade shave well again.
Finally, I am virtually certain that all the methods you may see on the internet, for stropping a razor blade, are simply folklore. E.g., rub the blade on the inside of a glass, strop it on denim, and so on. These probably date back to the era of carbon-steel blades. I’m pretty sure stainless is just too hard (or wear-resistant) for those to work.
Even a proper leather strop merely shined up and cleaned up my blade edge. It didn’t make it any sharper or better for shaving. Experts say that you need to use abrasives, if you plan to strop stainless on leather. My guess is that this is good advice. But unlike a knife blade, you can’t afford to lose even a smidgen of metal off the edge of a razor blade, or it will no longer function in a safety razor. So I don’t think abrasives are the answer here. But I have to note that I have not actually tried loading up a leather strop with the proper stropping abrasive and having at it.
So, the only other object commonly used for cleaning up the edge of a stainless blade, without abrading it, is a knife steel. Knife steels definitely work on stainless knives. There’s no reason to think they won’t work on stainless razor blades.
And, near as I can tell, yes, steeling a stainless razor blade in this fashion does something. Kinda. I guess?
So with that, I’m calling it a day.
I’m ready to call it quits on trying to strop a stainless-steel double edge razor blade. For now, at least.
The only thing I’m fairly sure about is that effectively honing or stropping a stainless-steel blade will probably require some sort of abrasive. But … if I abrade away enough of the razor edge, the blade will no longer function (see prior post).
So it’s possible that this has been a fool’s errand. Or it’s possible that I don’t have a good grasp of how much damage can and cannot be repaired by honing or stropping a stainless-steel razor blade.
Here’s a sequence of photographs, starting with a beaten-up blade, and ending with a blade that was honed using Brasso, an abrasive metal cleaner.
1: Original condition, note the nicks in the leading edge of the blade
2: After honing in a large-diameter piece of borosilicate glass. This was a PYREX measuring cup, and best guess, that’s about the diameter that antique glass hones would have matched. I’m not really seeing a whole lot of change in the nicks.
3: Hone on medium-diameter borosilicate. I’m certain this was smaller diameter than implied by antique glass razor blade hones. I’m still seeing no marked improvement in the nicks.
4: Hone on very mall diameter borosilicate. Maybe some of the nicks look a bit less sharp. Maybe that’s my imagination.
5: Leather strop, dry, 20 strokes of the razor, on 6″ strop. The surface is nicely polished, but the edge is still a mess.
6: Extensive honing using Brasso on medium- and small-diameter borosilicate. The abrasives in the Brasso were evident (it felt gritty to move the blade against the glass), and maybe this smoothed down the nicks in the leading edge of the blade.
Rubbing these blades across any of the tested surfaces, without abrasives, didn’t seem to do much. Plausibly, there’s something happening to the absolute edge of the blade. But in terms of smoothing out those (almost microscopic) nicks in the blade, it was no go. I think that’s consistent with expert advice to use abrasives when honing a stainless straight-razor.
Honing with abrasive Brasso on curved glass maybe did something, maybe not. Definitely maybe kinda smoothed over some edges on the nicks in the blade.
But, at the end of the day, if you compare the rough, pitted edge in the first couple of photos, to the edge in the last photo, I’m not sure I’ve done much.
For now, I’m stumped.
First, it’s possible that I simply don’t understand what honing or stropping is capable of doing to the edge of the blade. Maybe a blade like the one above is beyond help. In which case, I’m not sure what honing or stropping is going to do for me, for a stainless blade. Because if the blade is in much better shape than that, chances are it shaves fine.
Second, no wet-shaving experts try to hone stainless blades. It’s obvious, from reading well-informed discussion on wet shaving forums such as Badger and Blade, that wet-shaving afficianados will, occasionally, strop old-fashioned carbon steel razor blades. But nobody strops stainless razor blades. To the contrary, every mention of stainless and stropping/honing boils down to “they last longer, but you can’t strop them back into shape, the way you can with a carbon-steel blade”. So, not even die-hard wet shaving fans mention any way to strop stainless razor blades.
Third, I already noted that stropping died out when stainless steel took over the blade market. I am certainly that traditional stropping methods should not work (or work well, or work easily) on stainless, owing at least to the greater hardness of the steel. Even straight razors — where stainless steel razors can be stropped — require use of an abrasive. That tells me that traditional materials used to strop carbon steel just won’t cut it.
I’m really left with just two more things I can try.
First, I can add abrasives to the leather strop. Plausibly, the combination of abrasives and the pliable backing will carry those abrasives into the nicks in the blade and scour them out.
The drawback to that is that the only way I have to strop a blade is to run it over the leather strop while it’s in my razor. (Even that’s not ideal — I’m pretty sure the razor blade does not sit at the correct angle when I do that.) In any case, I don’t want to subject my razor to the abrasives in Brasso or similar. So I need to buy or rig up something to hold the blade, if I do that.
Second, I can buy one of those mystery devices that claims to extend the life of razor blade cartridges. (reference, reference). Those work by stropping the stainless-steel blades contained in the razor cartridges. Some people swear they work. Others say they don’t. The real question is whether I want to spend $10 on something that I’m betting is a scam.
When all is said and done, if I get motivated, I’ll try one more thing. I’ll buy or make a device to hold the razor blade at the correct angle, and try stropping with a leather strop and the proper abrasives.
At that point, if that doesn’t do it, then I’m done. I’ll judge that stropping or honing a stainless-steel razor blade is a fool’s errand.
