The Special Projects Division of Prometheus Design Werx has released their newest iteration of the Invictus folding knife design. The Invictus-IL features a unique handle machined from a solid block of titanium billet.
That’s not surprising as the company often uses titanium in its innovative products. This form of folding knife handle construction required the brand several years and as many machining centers to finally develop, produce, and deliver the highest quality of make in this folding knife. If you’re looking for that special EDC folder, this might be it.
