These things are good! After use and abuse, they still cut a sheet of paper more accurately than fresh scissors. They cut nails, screws, wire, sheet metal and don't dull at all. I've used it as a base to hit things in hard to reach places and as a hammer myself when I dropped my hammer 30 feet and didn't want to grab it. I dropped this 40 feet onto reinforced concrete and only the concrete was damaged. I've cut 1/4 inch steel cable at the tip of these dozens of times and the ends were as out of phase as a nuclear warhead with room temperature oil. 3 of my colleagues have already bought their own after using mine. I'd say buy two of these but I couldn't ruin the first pair so I don't see why you need a second if you don't want a pair for your truck.
