ROZAKA — World’s Smallest Utility Knife for No. 11 Blades
Couldn't be smaller. Couldn't be sharper. Surgical precision right on your keychain · Patent pending
About This Project
The ROZAKA is a utility knife machined entirely from stainless steel, featuring a replaceable No. 11 surgical blade and a seven‑part, fully serviceable design with no plastic or proprietary fasteners. It has endured hundreds of open‑close cycles and real cutting tests on wood, leather, rope and food without failure, demonstrating exceptional durability. Because every component can be repaired or replaced and the knife is 100 % recyclable, it is built to last a lifetime and minimize waste. The project aims to move from prototype to reliable series production, with an estimated delivery of January 2027.
