The shave is our goal and there simply is no standard way to quantify, by measurement units, a "smooth shave" and/or "a sharp shave". If 5 users test the identical razor they will all likely...

His peers would be another Engineer with experience and/or training in Metallurgy/Materials sciences. The vast majority of us, if any, are not one of his peers.

Agreed. Until we all agree on a set...

I think it may be possible; limited by the particular steel's ability to repeatedly bend over an ≈ 15 degree arc, from each stropping stroke, without breaking off. I am just guessing.

I think the...

Too bad he wasn't more specific. It's probably too late to ask Mr. Martin now. Even if he meant plain leather, his conclusions still wouldn't settle the issue of "how abrasive is leather?".

Abrasive action is due to friction, especially if the objects are in motion.



Here's how I see abrasion: anytime you rub 2 friction surfaces together, you have abrasion of at least one...

I agree that canvas/linen is more abrasive than plain leather, by far. I always find more metal particles on vintage canvas than I do on vintage leather. I have picked up razor splinters from both,...

I just said in my last post, "That friction is precisely why you have an abrasive action...". It seems that we are in complete agreement about that, then.

Precisely...

I like the Engineering...

In the book's link, Butz says that he sometimes uses "a little polishing compound". The implication being that he more often does not. That's a long way from "always advice to dress the leather with...

I can and do regularly remove small burrs (on German and Swiss chipcarving tools, mostly) all the time. This is sometimes done using plain leather on a flat surface. Here's a reference by just one...

I couldn't help but giggle when I read that a plain leather strop couldn't remove a burr.

This will come as a big (and humorous) surprise to hundreds of woodcarvers and knife sharpeners who do it...
