I've been using the leatherman charge for a few months now, I haven't had a problem with it. i own a small horse farm and use it everyday. I clean and oil mine once a week along with my pocket folder and other gadgets i walk around with. sawdust is murder on equipment! gets in every nook and cranny! i use compressed air in a can to blow all the dirt out. had other multi tools and they all failed one way or the other. leatherman holds up pretty good for me. all the blades and tools lock. knife dosen't hold an edge very good but its not bad compared to others.
