I have been carrying a pocket knife of one kind or another since I have been old enough to not cut myself. I've had a basic Buck 2 blade 'canoe' knife in my pocket for years. Most often used for cutting plastic ties off of paper boxes at work, opening envelopes or hacking through some of this crazy plastic packaging you run into these days. I picked up a Spyderco Tenacious lock blade a couple of years ago and find its size and weight to be perfect. I picked up a CRKT M21, Carson designed assisted opening folder not long ago. Probably the closest I come to a "tacti-cool" knife. Really a nice little knife that fits perfectly in the little front fob pocket (or whatever) of my jeans. I forget it is there.
