For the reason the lock bar REALLY engages sometimes while other times it engages enough. I would use the flipper to deploy the blade and then switch my hand position to get a full grip and I hear the lock bar slide in the a little more. This makes is extremely difficult to disengage the lock bar. Is this normal and just needs to be broken in or is something out of spec here? Also, I find it really difficult to deploy the blade if you are gripping the knife and applying even light pressure to the lock bar. Again, is this normal and just needs to be broken in?
