Kershaw Junkyard Dog II. I got mine online for $49 shipped, it's the best linerlock I've ever used. the liner is incredibly thick, lockup is solid with 0 play in any direction, G10 handles, and silky smooth flipper opening. I love mine. If you are looking for something smaller or cheaper, then check out a Kershaw Skyline or Zing at the local wally world.
