I'm not sure if others are having this problem, but the clasp is so tight that it is difficult to undo it. I've had to stick a blade under the clasp to pop it loose sometimes.
So I took my diamond honing stick (for the kitchen knives) and did some very careful minor grinding on the mating surfaces of the clasp. And now it releases much more smoothly and with a bit less effort. Still very secure but much easier to release with a finger.
