when you use a simple stanley box cutter blade you feel as if you could shave with it. maybe you can but im not. anyway the reason is these are lower on the rockwell scale and take an edge very easily.

? So a harder metal dulls faster than a softer metal?

have heard many stories of G.I.'s over the years shaving with various bayonets. after owning quite a few bayonets and sharpening the hell outta them with stones or diamond blades i have failed to get one EVER to a razors edge. its your face if faced with shaving with juan.

I would think that this has more to do with the fact that the blades are thick (to be strong) and therefore are harder to put an acute angle edge on (probably a requirement for shaving).

But I'm no expert, educate me.
