The dynamic duo of Elliot and Chris Williamson, better known as Ferrum Forge, has earned a solid reputation for their large, aggressively styled custom knives—but the adept brothers have other tricks up their sleeves, too. Enter the RUK Titanium: the latest version of the small keychain-ready utility blade that weighs just 0.7 ounces (nearly half as light as the previous copper and brass versions). Featuring a slim 2.6-inch body, the RUK Titanium is compact, out of the way, and ready for any light-duty task. The spring-loaded blade is designed to retract automatically and stay put safely inside the body—it does not lock, so you don't need to worry about accidentally poking yourself while the RUK is in your pocket. To access the blade, just slide the stainless steel button forward as far as you need.
