The Un-Bo caught our attention with its agile and graceful style. This edition has a titanium chassis with a striking presentation side of dark maroon micarta. The Un-Bo has chamfered handles, a compound grind and smoke finished S35VN steel. The Un-Bo is reductionist in build, but not short on features.

The handle is an expertly contoured framelock of titanium and Micarta. Pared down to its essence, the knife is profiled to be thin and light, yet secure in the hand. The blade itself is a modified compound ground Bowie with Sheffield style clip. The smoke finish offers depth to the contours of the S35VN blade. Deployment by either the milled relief cut out in the blade or the flipper tab is robust and positive due to the bearings under the titanium pivot.

Finer details include a 3D titanium clip, pivot, stand offs and screws all finished in a subtle matte blast finish. Our logo is at the base of the blade on the presentation side while Simeon’s logo is nested in the lockbar relief. Finally, Jamie milled our triple fullers into the titanium slab.

Reduced to perfection, the Un-Bo is an effortless and capable EDC.


  • The S35VN compound ground Sheffield Bowie style blade running on bearings, can be deployed by the flipper or the milled blade pocket. The non-glare smoke finish is applied by hand rubbing, then etching and finishing with Scotchbrite. 

  • The presentation slab is made from maroon micarta with an inlaid titanium plate for strength. 

  • The titanium framelock is blasted for a muted and tactile finish. 

  • The titanium 3D pocket clip is finished in a deep matte blast and affixed by titanium standoffs.

  • Crafted titanium pivot and torx pivot screws are bead blasted to match the frame and clip. The etched Triple Aught Design is  at the base of the blade while Simeons is present in the lockbar relife.
