I've been a small engines mechanic for 4 years and on the job I use my Leatherman Wave pocket tool. It is one hundred percent stainless steel, so no problems with rust. It weighs 8.5 ounces. I have never had a problem using it but a person with not as strong hands might find it challenging. It has needlenose pliers, regular pliers, wire cutters, hardwire cutters, clip point knife, serrated knife, saw, scissors, wood or metal file, diamond-coated file, large bit driver, small bit driver, large screwdriver, ruler (8 inch/ 19 cm), bottle/can opener, wire stripper, lanyard attachment, and two double ended bits. So it is fair to say that you would be prepared with this pocket tool. Online there is a Bit Kit to go along with it to give you more versatility.
