I Waxed The Badger.
Correct. If we all had scanning electron microscopes we could see the crazy things our stones do to our cutlery.When honing a razor you do create burrs. What you don't do is create noticeable burrs - it's just a matter of perception and definition. And further - the definition of a burr or wire edge probably actually changes depending on what you're cutting with the blade...
In the knife world, basically a Scandi grind, though a razor usually has a hollow, but my point is the you lay the blade down to sharpen.a 'zero bevel', which is analogous to the edge of a razor.
Basically, but also an obscene number of pull strokes on some abrasives will create a foil edge which is too thin to be of any use. I don't think barbers ever did that, but I think some razor sharpeners these days cross the line between highly useable and over sharpened because time is not a factor. If you were a barber 100 years ago, once it was ready to shave, you quit honing and earned some money. Today we futz and fiddle the hours away.A razor has what, on a knife, one would consider a wire edge. That is why it is so sharp.
