Hopefully we can devise tests that we can do with just a strop and razor, using our face as the test instrument - these are the conditions in which we hope to make use of this information, after all....

Actually Verhoeven's photos do show teeth, but only when honed with fairly coarse grit hones. As the hones got finer and the size of the scratches became comparable to the thickness of the edge then...

It may take more laps than that. Remember we're talking about reversing a process that takes a week or two to dull an edge, during which time it has recieved a thousand or more laps on the...

I don't know. This is a problem with that part of the paper.





The Verhoeven paper wasn't published in a peer-reviewed journal, it was just a write-up of some experiments he did ,and if it...

Steel at razor levels of hardness isn't terribly plastic at all, and the temperatures needed to significantly increase plasticity will kill the temper. It's possible that a good stropping on leather...

I don't think the leather strop does anything but align the edge. Neither Verhoeven nor the Modern Mechanics article from the 20's showed any sort of steel flow or stretching. Verhoeven also shows...

But that report didn't say which side of the strop was abrasive. The two reports are consistent if the linen side of the strop is the abrasive side.

The stropping-on-plain-leather experiment was done in two different parts of the test (honing and tormek) in two different conditions (lab and a workshop) by two different people (Verhoeven and...

He didn't post the edge dimension. But if the strop couldn't even straighten out the burrs it's unlikely to have drawn out the thicker bevel.

Hmm, we're talking about the same document. I just went back through it searching for "felt" and it appears that I was mistaken and he used the white bar on the felt and cloth in all experiments.
...

Yes, plain hard felt did sharpen the edge - this could be clearly seen under the microscope. He was stropping with the blade slightly inclined, so the felt produced a secondary bevel, but presumably...

He does test a commercial gillette blade and a straight razor honed by somebody that shaves with one at the very beginning of the article.




I think the mentions somewhere in there that the...

I think it's the linen that's doing the work of sharpening the razor though. You'll notice that he also tested felt strops and they did sharpen the steel. He didn't test linen but I suspect they...
