I guess I'd have 3 different kinds of hard-use folders:
1. The used, abused, and retired
2. The current user that's abused
3. Ones that I KNOW I can trust 100%
For #1 I have my 2003 Emerson Commander. It's done light chopping, batoning, slicing, opening cans, gone fishing, been to the beach several times, struck a ferro rod probably 500 times and made 2 actual fires

. This thing just kept coming back for more. It's not carried anymore but it sure as hell is my go to knife for keeping my current EDC's in perty condition.
For #2 I have 3 knives that I use and rotate on duty and on my off time: The 2010 Cold Steel Ak-47, the original Cold Steel American Lawman (with steel liners), and my newest addition the Benchmade 806D2 AFCK. The 2010 CS AK-47 is an amazing knife. It's stabbed all sorts of things and the aluminum pommel (aka pinky guard) is great for window breaking too

The wave feature is OK and that's because I have a 4/5 chance of waving it open the first time. The CS American Lawman is incredible.....nuff said. Demko got it right and I'm very glad that it's at an affordable price range for me to be able to enjoy a smaller version of his custom. That knife has been to hell and back since I became an Officer and even before that on campouts and fishing trips. The 806D2 AFCK is a great knife that I plan on putting through the ropes on duty.
For #3 I would say that I can 100% trust the CS American Lawman (with steel liners) for anything I can think of doing with a knife. I would love the custom version, just not at my pay grade right now.
