A Keychain-Ready Sidekick, Now in Titanium

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: a brand-new 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. To access it, just slide the stainless steel button forward as far as you need.

Note: At checkout, choose black (PVD coated and stonewashed), blue (anodized and oil sealed), or gray (stonewashed). This drop is limited to 1200 total units. 

First-Run Production Perks

When you join a drop before it goes into production, you’ll get a few exciting perks:

  • Exclusive titanium lanyard bead with matching finish
  • Length of paracord to attach bead

Office-Friendly Design With a Sure Grip

Don’t have room for a folding knife in your daily carry? Need a secondary edge for smaller cutting tasks? Want an office-friendly tool that won’t raise eyebrows every time you take it out? The RUK Titanium covers all the bases. Milled with a textured case back and finger groove, it’s designed for a secure grip. The domed button slides easily on the track when you're ready to put the blade to work, but it won't catch easily on your pocket. Among the tool’s many uses are opening packages and letters, cutting threads, crafting, and scoring paper, plastic, and cardboard. Carry one every day and you’ll find plenty more.

About Ferrum Forge

Founded in 2009, Ferrum Forge started from humble beginnings in Elliot Williamson’s garage in Southern California. Using found pieces of steel like old files and leaf springs, Elliot gradually taught himself the art of knifemaking and metallurgy. As his skills and passion grew, so too did the demand for his work. Luckily, Elliot’s brother Chris joined the team in 2012 to help expand Ferrum Forge to what it is today: a small operation dedicated to designing and producing custom knives through a rigorous process of development, machining, iteration, and quality control.
