do you use the fluorinated grease, or just regular oil? the reason I ask this is that Chris reeves knives are so strong in tolerance that oils don't have the same protection and could ware out the pivot and lock bar. this could cause the blade play. when people grease, many of them don't grease the tang or the ball on the lock bar. the tang gets the greatest of all tension.
Wait, are you talking about putting grease on the lock face and blade tang? Cause I wouldn't recccomend having any lubricant in the locking mechanism.
