Overview
The Subrosa is a collaboration project between Ken Steigerwalt and Matt Lerch. They have patent pending status on this mechanism. They have sold the manufacturing rights to Benchmade, who will produce factory versions utilizing this mechanism.The key elements that make this assisted mechanism a cut above are the two titanium leaf springs connected together with a hardened roller that engages on the blade. Because the roller follows the blade during the opening and closing motion, there is little to no wear to the components. Matt makes the frames and various components, while Ken hand grinds and hand finishes the blades, makes the pocket clips, and completes the assembly.
