Likes Boring Knives
It seems to me that the only difference between a burr and a knife is that the knife is less likely to bend.
It would be theoretically possible to thin an entire knife so much that it was one 50 mm tall burr from top to bottom. Just like the usual kind of burr, it would be extremely sharp but would collapse under pressure.
I don't know the proper name for it, but clearly every knife has a "critical thickness" - if it becomes thinner than that measurement, it will collapse when used. Sort of the point at which it stops being a knife and starts being a burr.
Do different knives have very different "critical thickness" numbers? Or would they all be about the same?
And ... is all of this BS? If it is, then is it easy to tell me why?
