Sumo, Titanium with Satin Finish, CPM-20CV Blade Steel, Bronze Anodized Accents

Notify me when back in stock.


We named this knife the Sumo, because once you see a Sumo up close and in person, it’s not something you’ll soon forget!  What makes this knife unforgettable is that it’s a button lock flipper with multiple opening options!  You can open with thumb studs, you can use the miniature hidden flipper tab, and you can also use the pocket on the blade to open this knife…  And finally… To fully appreciate this next opening option you’ll have to watch the video below.  (Hint – you can auto pocket-edge open this knife as well!!!)

Our goal was to lighten this beast while keeping it amazingly strong, so we 3D-machined it inside and out.  This is our first button lock flipper! (And what a challenge it was to pull off!)  And finally, we added a little “bling” by anodizing the thumb studs, pocket clip, and backspacer either Bronze or Blue – very subtle and muted colors that set off the look of the knife in a way we haven’t tried before!

Overall, I’m very, very pleased with how well this knife turned out!
