Ketuo Knife Dirty Bird FAQ

The Ketuo Knife Dirty Bird blends ornate custom styling with functional everyday cutting performance. Featuring a 3.75-inch Böhler M390 Wharncliffe blade, full titanium handles with exotic inlays, and a button-actuated lock with a built-in safety, this series offers standout design and practical utility.

What lock mechanism does the Ketuo Dirty Bird use?
The Ketuo Dirty Bird uses a button-actuated top liner style lock equipped with a secondary slide safety. Pressing the button lets the blade swing freely for smooth, finger-safe operation without your fingers crossing the blade path. The integrated secondary safety switch blocks the button from being pressed when the blade is deployed, preventing accidental lock disengagement during heavy cutting.
How do you open the Ketuo Dirty Bird?
The Dirty Bird offers three different deployment methods: dual thumb studs, an elongated blade opening cutout, or pressing the lock button to flick the knife open. These multiple options allow you to choose between standard manual opening or rapid, button-actuated deployment.
What blade steel and shape does the Dirty Bird have?
The Dirty Bird features a 3.75-inch Wharncliffe blade made from premium Böhler M390 stainless steel. The Wharncliffe geometry provides a flat, powerful cutting edge with a precise utility point, while M390 steel ensures long-lasting edge retention and high corrosion resistance.
What handle options are available in the Dirty Bird series?
The Dirty Bird is available in three titanium handle finishes: polished blue, gold, and blasted gray. Each version includes distinct decorative touches, including exotic pattern inlays around the pivot, blade sculpting, and file work detailing across the titanium pocket clip and two-piece backspacer.
Why is the Ketuo Dirty Bird so popular among collectors?
The Dirty Bird offers high-end custom knife aesthetics and premium materials in the $265 price range. Between its Böhler M390 blade, full titanium construction, exotic inlays, and unique lock safety system, it provides tremendous build quality and functionality for enthusiast buyers.
