My Benchmade 551, with a black coated plain edged blade. I bought it for a princely (for a college student) sum of $89, which dug pretty deep into my savings account at the time. That was about 5 years ago, I think, and since then I've smoothed out the handles a bit, bent and re-bent the clip, stonewashed the blade, and touched it up on the Sharpmaker I don't know how many times. It's taken a lickin and keeps on tickin, its still my choice for a full size tough folder. I need a backup though, I'd hate to lose it somewhere.
