When I say destroy, I mean I put them through their paces. I cut wood, wire, scrape thinset, foam insulation on concrete, pry back some trim on occasion, if nothing else is handy, cut open boxes, plastic wrap, etc... I have a CRKT M21 that has held up nicely. It is constantly on the sharpener, and the profile of the blade is disappearing. I tried a Kershaw Needs work, and the tip broke the first day, and a few months in, the knife needed cleaned, but the pivot had stripped in the zytel handle. I have taken my para military a few times, but I just can not bring myself to use it at work. My knives from work are not pretty, but they serve me well. I have a nice collection of higher end knives, but when I save and sell things to be able to purchase a Chris Reeve, I am not taking that to work. I would wrather buy one 30 dollar knife a year.
