May I ask what you're doing to your Leatherman tools to cause them to fail? I've carried one variety or other since they first came out& the only failure I've ever had was a broken file that I was (mis)using as a pry bar. My current Supertool has been with me since '96 and has seen almost daily use. It only recieves a touch up on the Lansky as needed and an occassional shot of WD40. I just don't see a potential failure short of blatant abuse
