IMHO, keep the knife. If you want to put it in your vehicle kit, OK, but I would keep it at home. Get something different for the vehicle - plenty of discussion here and at knife forums about that sort of thing. You can afford the weight for a hatchet, axe, froe, saw, whatever, so as little as $10 for a stainless Mora will net you a good, useful knife for the Jeep. Or a Leuko (sp) set of a large and small scandi-type knives.
