Unfortunately, it depends a little bit. The compression locks, it seem, can be a bit sticky at times, but one that works well is one smoooth operator. The lock on the ATR is to me pretty much the lock Nirvana: Integral compression lock doesn't get better than that. Again some people have reported that they pinch themselves unlocking it. I have never really gotten to like the bladeshape of the ATR. Maybe I will change my mind, but sofar I am still hoping they will come out with a new knife that uses the integral compression lock (and hopefull has a Ti handle aswell...and a leaf blade....
, I can dream, can't I...
)
