I had one and did think it was a pretty good knife, but I found that I didn't trust the lock. It's a bit different than a regular liner lock in that the liner bends in the opposite direction than typical liners. It actually wants to go back to the
"un-locked" position and the button that disengages the lock actually pushes it into the "locked" position. It failed on me with a couple of very light taps and wedged itself into a position that required a pry back into position in order to close it. After this, it wouldn't engage consistantly into a "locked" position. And when it did lock up, there was play in the lock. Good overall idea, but lacked in strength, IMO. I bought for work as a firefighter, but wouldn't trust for it's intended purpose after this.
Hope this helps.
