I bought my Rat Trap when they were first introduced. I carry and use it daily. I wouldn't go as far as to say I abuse it but I never think about "taking care" of it. If I need to use it for a tough job I use it. Period. After several years of such use, it is still in great shape and is still my only EDC folder. My other folders (including a Spyderco Military, which is as close to the RT as you're going to get) are now kept in a drawer. I keep thinking I'll end up getting a Sebenza once I wear out my Rat Trap, but the damn thing just keeps performing. It probably could use a bit of a tune up at this point because the lock up isn't as smooth as when new, but it's one hell of a knife otherwise and definitely one of the best that Swamp Rat has produced thus far. I wish they still made them.
