I was always interested in the LCK but the scales we're appealing to me. This one looks better. All black with G-10 scales and hollow ground blade. Assisted opening works well and it also snaps into closed position with plenty of retention.
The pocket clip has a tall opening at the front but then the clearance is a bit tight. It won't fit over thick material.

I bought the CRKT LCK just because it looked like a fun, relatively inexpensive knife. I quickly realized this thing is a great knife capable of strenuous tasks and with an explosive flipper. The blade came razor sharp.

This knife is like a larger, thicker bladed version of the Inara (Rogers design), one of my favorite knives. The CRKT LCK is a tough knife, one I don't ever worry about breaking the tip on. I highly recommend it.

What a great little knife. A few minor tweaks and a lube job getd this thing deploying faster than any a/o knife in my collection. The blade was razor sharp it of the box with the grind being better then I've had on knives worth ten times as much. The reverse tanto/modified Wharncliffe is beautifull. Did I mention this thing disappears in your pocket?
First crkt over owned in years and in mighty impressed. In think I'll buy a spare
