This special edition of 250 pieces, designed for the 25th anniversary of the brand, maintains the shape of the original knife but with up-to-date materials and finishing. K1 has a modified spear point blade, whose tip is a combination of tanto style at 40° and a more traditional European style, resulting in a very sharp but solid hybrid. It also has a sharp false edge that makes it very effective at thrusting. It has a high bevel that allows a very efficient cutting edge. The blade can be recognized for its hole on the blade, which makes the knife significantly lighter without compromising its sturdiness. It is made of Böhler N690, heat treated at 58 HRC, to reach the best combination of edge retention and resistance. It has a satin finish and a flat grind. The Anticorodal anodized handle has a lighter design compared to its original – a design that characterises Extrema Ratio knives – but it keeps the arched shape and the lateral “bump” of the K1, allowing an excellent grip in bot saber and reverse mode. The bottom part of the handle is curved to create a sort of hook for easily and rapidly pulling the knife out of the sheath, whereas the pommel stick out as a triangular glass breaker that can become a lanyard hole. The leather sheath is the exact replica of the original, retaining its features of rapid and easy extraction. The knife can be carried upwards underarm, horizontally with a belt or tactically in the leg. K1 comes with a Polypropylene case, a complete leather sheath and a shoulder strap to carry the knife underarm.
