Edge Retention/Rolling Test Stand

[Mark Reich]

 There are a lot of opinions and guessing going on there.  All of the posters could benefit from a sharpness tester.  You know, sharpen the blade, test the sharpness, cut some cardboard and then test again.  I suspect that some of those guys who claim their edges don’t roll may well be surprised at the results.

With all due respect, I don't think I've heard of anyone here cutting stuff. Like... never. Beg though I have.

Cardboard is a very silly thing to cut. There's absolutely no consistency. "How thick?" "Did you cut with the corrugations, or across them?" I've never heard anyone make any distinctions. Just, "I cut some cardboard". Hmmm.... 

It's also a pain because there'e so much drag involved with pushing the entire height of the blade through a stiff medium. There could be some torque involved. I don't know. I've only cut cardboard that actually needed to be cut. Can't say it's ever rolled an edge without hitting a staple.

This is not to say I've only cut a little cardboard. I was in the building trades for a few decades. I just never thought it was good testing material.

I Have made 50-500 cuts of manila rope.... I'd guess over 200 times. Who knows, could be over 300. Edges don't roll for me. They actually get Dull. Every damn time.
