PDW Invictus™ Alpha Semi-Custom


Prometheus Design Werx's signature, mid-sized Invictus™ Alpha folder design as made by Calavera Cutlery (Jeremy Robertson). Purpose driven, engineered, high grade edged tool crafted in CA by a former pilot turned knife maker.

Precision crafted in CA, the Invictus™ Alpha Semi-Custom folder design is an instantly recognizable aesthetic and styling, characteristic of a purpose driven, lifelong design direction, and ethos. This folder is inspired by and takes its design cues from the tried and trued millennia old spear point blade silhouettes, to the tapered capsule shapes, streamlined arcs, and the purposeful fluting and texturing of the modern machine age as found in high grade tools to precision barrels. Coming in at a mid-sized blade length, this folder is a high grade Semi-Custom edged tool for users and collectors who prefer a 3.5" blade length in their folding knives. The Invictus™ Alpha Semi-Custom features a fully contoured (requires up to 5X the mill time to achieve than a flat handle) custom made titanium handle, machine ground blade with fuller, our PDW mark, deep cut handle fullers, billet pocket clip, lanyard pin (for 3mm cord), and secure robust jimping through-out.
