Define hard use. I have many folders that are tougher than the Manix 2 (stouter blade, stronger lock, thicker tip), and yet I've never really come across a chore that the M2 couldn't do. As with most Spyderco's the tip is relatively delicate, but that's about it. For practical purposes the M2 is a very good folder. Practicality is not all there is to knives however, and for that reason most of us own many of them. It's just nice to own a folder that can purportedly handle a 1000 pounds of stress on the lock.

Even if the knife never does more than cut pary ribbons!
