This is a crkt Crawford Kasper folding knife in good used condition opens and close  smoothly and locks up tight. the safety for the liner lock which prevents the liner from being released while it's in the open position is in working order but the little black button that it came with is missing in action, you can see what I'm talking about in the pictures it does not affect this locking mechanisms working ability,...look at all pictures, they are part of the description and show the condition, the dimensions and the exact item you will receive.
