It seems to be a function of the framelock, i.e. if I hold the lock tight in my hand with the knife open, I get no play. The lock is functioning properly as my hand holds closed tighter. But without holding it, I can "look for" play in the lock-up, by wiggling, and damn if I don't find it. The lock-bar moves a tiny bit and makes little noise, and the blade wiggles almost imperceptibly. Should I take issue with this? Is this standard behavior for a framelock? When I move my thumb and forefinger back and forth on the jimping, the blade moves ever so slightly (but like I said, not when my hand is gripping the handle tightly.) What do you guys think? Should I send it in to Strider?
