Description
The Concept: Piedra Negra Fighter Knife
The Piedra Negra Fighter Knife is a masterpiece of surface treatment. We forged this blade from SAE 5160 steel with a 5 mm thickness. Furthermore, we applied a unique phosphatized “stone-like” finish. This technique provides excellent oxidation protection. Consequently, the knife gains a sober and unique visual identity. This model is a highlight of our Signature Series gallery.
Materials and Ergonomics: Acacia & Bronze
The handle features Acacia Arca Viscote, a highly resistant native wood. Additionally, we integrated a solid bronze bolster to balance the total weight of 475 g. This ensures precise handling and a comfortable grip. The combination of dark wood and bronze creates a sophisticated aesthetic.
Hand-Chiseled Sheath and Dimensions
This knife has a total length of 328 mm (12.9″). Therefore, it offers great reach and power. Each piece includes a premium cowhide leather sheath. Our artisans chiseled it with geometric patterns and stitched it by hand. This ensures a perfect fit for the 190 mm blade. Visit our Available Now Shop to see other unique creations.
