If you can only carry one tool for personal defense/burglary, make it the Ka-Bar Becker TacTool ($140). The result of a collaboration between John Benner of the Tactical Defense Institute and Ethan Becker of Becker Knife and Tool, the TacTool offers a 7.75-inch blade, and works for prying open doors or windows, cutting, bashing out windows, lifting nails and hinge pins, and more.
No matter what the job, the Leatherman Super Tool 300 ($70) is ready to handle it. This heavy-duty all-purpose tool offers both a clip point and serrated knives, both needlenose and regular pliers, several wire cutters, a wire stripper, a crimper, a host of screwdrivers, a file, a saw, both bottle and can openers, a ruler, and more. With rolled handle edges for a comfy grip and rock solid stainless steel construction, it's ready to help with your handiwork for years to come.
Take a trip back to 1891 with the Victorinox Swiss Army 125th Anniversary Heritage Knife ($495). Limited to just 1884 individually numbered units, the Heritage is a replica of the 1891 "Soldier's Knife" made by Karl Elsener for the Swiss Army. It features a large blade, punch, can opener, screwdriver, ebony hardwood handles, a certificate of authenticity, and will arrive in collectible commemorative packaging.
Swiss Army knifes are incredibly handy tools, but not everyone wants to own the traditional red model. The Victorinox Swiss Army SwissChamp Hardwood Knife ($100) is a great compromise, offering all the utility of the original — including large and small blades, a corkscrew, can opener, bottle opener, screwdrivers, and more — wrapped in a handsome exotic wood exterior.
About as long as a credit card, this low-profile knife can be discreetly carried just about anywhere. Made of black powder-coated 9CR18 stainless steel, the Ka-Bar Last Ditch Knife ($15) comes with a hard-plastic friction sheath and 30-inches of black 550 cord. Slip it in your bag, keep it in your wallet, hang it from your neck, or lace it into your boots.
