Instead, carry a roll of vinyl electrical tape. For less than a buck from your local hardware store, vinyl tape is substantially cheaper and easier to use than duct tape for everything from a temporary electrical splice to fixing a broken reelseat on your favorite bass rod. If that makes me sound like a deep-woods Bob Vila, so be it. Among tool sets, these are the best deal. Here's a quick check of what you might want your set to include.
Many sets use interchangeable bits with a single handle.
Add some Torx bits for the star-shaped screw heads that are increasingly common on newer vehicles and other machines. You need three. Long-nosed pliers for reach usually also include wire cutters. My knife lives in my pocket, and the small axe stowed under my truck seat takes care of the hammer part.
