The Schrade X-timer caught me by surprise as I was shopping for Yule gifts in 2002.  Wandering the aisles of Wal*Mart, I found these knives clamshell-packed and hanging from a shelf.

With a three and a half inch black-coated blade, thumb disk, and pocket clip, the knife is obviously intended as a tactical folder.  The handle swells to a very minimal guard and has a lanyard hole at the end.

As it is a rocker-bar lockback, I was inclined to trust the X-timer more than a Schrade linerlock.  (To be honest, Schrade's linerlocks have never been to my liking, particularly on the "Cliphanger.")  I bought two X-timers and discovered that one had a little blade play (up and down) when open.  The other was nice and solid.

The aluminum handle slabs are cross-hatched and very "grippy."  The removable metal clip is configured for "tip-down" carry, which is what I prefer.

If you're looking for a reasonably inexpensive, locking, pocket-clip folder and you find yourself close to a Wal*Mart, check for the X-timer.
