I dropped mine off a 30 story building. The lock held up just fine and the blade stuck into the concrete all the way up to the choil. When I pulled it out (actually, I had to use a jackhammer to get it out), the finish wasn't even scratched. I then tried to cut the blade with a cutting torch. It didn't even get the blade warm. It's one tough folder.

Hoodoo
I get some pleasure from finding a relentlessly peaceful use for a combative looking knife.
