recently i got a CRKT point guard large with half serrated blade. the more i play with it the more i notice side to side play when the blade is closed. once open the lockup is solid it is only when closed that the play is noticable. is this a common problem with the point guards? should i consider taking it back or is this relativly common among these models? i ask because i also own a CRKT M16-14 and that sucker is solid no play at any time
i know these are not expensive knives but just wondering if i should be concerned with this. i know a small wrench can be used on it so should i just tighten the screw down that is over the blade pivot point? just a novice so any help greatly appreciated
