The Jake Hoback Sumo is a standout in the world of high-performance folding knives. Named after the power and presence of a sumo wrestler, this pre-owned knife is just as unforgettable. Featuring a button lock flipper mechanism, the Sumo offers multiple ways to open the blade, giving you flexibility and control: use the thumb studs, the hidden miniature flipper tab, or the pocket on the blade for easy one-handed deployment. For those who prefer a little flair, simply depress the button and swing the blade open with a flick of the wrist.
 
Designed with lightweight strength in mind, the Sumo is 3D-machined inside and out, achieving the perfect balance between durability and performance. This marks Jake Hoback’s first button lock flipper design, and it’s clear he’s a natural—his execution is flawless. With its robust build, precision engineering, and sleek lines, the Sumo stands out as a versatile, mainstream contender in its size category.
