Earlier today, I had to break down a whole 'lotta cardboard at work. I carry a Great Eastern Cutlery #15 Boys Knife from the latest run with acorn shields and 440C blades. When I first started buying and carrying knives again, all I wanted was M390. Just couldn't fall in love with any of the modern folders I tried, though. Not really a fan of high carbon non-stainless steels, I like the way they sharpen and I think patina is cool, but I'd rather not fuss with it in the end.
I have read a lot about edge retention and sharpening and all of that stuff, and I sharpen all my knives myself. I like it as a meditative activity, and I take pride in carrying a knife that is so incredibly sharp that it impresses me.
Anyhow, I wanted to show just how much cardboard I cut up with nothing more than well-tempered 440C (disclaimer - I cut 75% of this, and then a pretty woman stopped by to say hello to me, who happened to have some kind of really cool little damascus bushcrafter that a friend of hers made for her, so she cut a little bit up, too).
Both of those 96 gallon cans are slam full. The knife doesn't shave anymore, but it still makes clean cuts in the cardboard. 5 minutes on the stones is all it's going to take to bring the edge back to screaming. I think this is a testament to 1) How capable a "lower tech" steel can be, and 2) that thing that knarfeng is always on about... what was it? Oh, yeah, blade geometry!
