i was wondering if a sebenza hasent been used hard, how often does it have to be lubed. I ask this because ive had many benchmades with phosphor bronze washers and i never lubed them. I know its been asked before but does the face on the lock bar need to be lubed? I wouldnt think the washers need that much lube because they really arent under any kind of sheer load. Also i use my sebenza on food, so i need a food safe lube any ideas...maybe baby oil ???
