It's not exactly a switchblade, but it's as close as you're going to get while staying on the right side of the law. The Benchmade 581 Barrage Knife ($220-$235) offers an AXIS Assist locking mechanism that helps you get the blade out in a hurry when it's needed — such as when fighting off rival gang members angry flocks of chickens — and a reversible pocket clip to keep it handy. Available with a plain, ComboEdge, or black-coated blade.
Inspired by professional mountaineer Ueli Steck, these new Wenger Titanium Knives ($140-$200) promise maximum utility in a lightweight package. The blade on all three knives is 50 percent thicker than standard blades and offers six functions, while — depending on the model — you'll also get extra appendages like a wood saw, bottle opener, file, wire stripper, can opener, and key ring.
We're big fans of minimalistic wallets, but we're not sure we've ever seen one that doubles as a knife. Designed by John Kubasek, the Creditor Carbon Fiber Money Clip Knife ($200) is a cunning combination of materials and functionality, featuring a carbon fiber and titanium body that folds to become credit card size — hence the name — while a clip holds your cash and cards, but press down on the side of the handle and it unlocks to become a handy six-inch blade. It can even fit into another wallet with the clip removed. Just be careful not to inadvertently cut your money in half — nothing says "shady" like paying for your Starbucks with a taped-together twenty.
