SAKs And Their Limits

[rhino]

Try cutting some skateboard tape/nonskid tape with your SAK or any other knife. That's a real test of edge holding. I've never had an SAK last more than a couple of cuts without needing significant resharpening after cutting really coarse nonskid tape.

Sandpaper might be easier to find for use as a severe test of edge retention.

In fact, assuming that it's the abrasive residue in carboard that's the "test," why not use 1200 grit sandpaper for uniformity? Well, there's the price.

I've got plenty of griptape around, it sure does a number on knife edges.

Maybe I can come up with something, like cut 1 foot of griptape, then cut X test material, then keep doing another foot and repeating the tests.

Although I'm a fan of M-Tools I must say that the knife steel is not much better than the SAK in most examples with the exception of the Leatherman Charge that has 154cm and even that I don't think has a premium heat treatment. I'm going to check the new changes in the locking screwdrivers that you have mentioned. My SAKs are older than 6 years.
