I picked up a partially serrated Vapor II at wal-mart earlier this week... and I've been carrying it daily since.
My Commander needs to go in for repairs soon, and until I get that taken care of, the Vapor works very nicely for that.
For like $23 this knife is a hell of a buy... smooth... solid lock up... tight, but not too tight clip... great looks... feels great in the hand...
My only concerns are these: The serrations are cut really deep... and I would worry about them snagging on clothing in a defensive situation. And, I usually dont like all metal handled knives, because of the issues of slippage when covered in blood/sweat. There are some nicely done traction grooves toward the butt... however I dont totally trust these.
But next time I am in town, just pick up a little some skate-tape/stair-tred tape, and cut to fit, and I'll be ready to rock.
Great knife, especially for under $25... probably the best buy I;ve made in a long time... wouldnt mind picking up another one, or two, maybe a small and another large, both PE.
