This special edition in 250 pieces, proposed on the occasion of the brand’s 25th anniversary, maintains the shape of the original, but with current materials and finishes.
The K1 is equipped with a modified spear point profile blade, characterized by a tip that combines the 40° “tanto” profile with the more traditional European one, creating a sharp but very solid hybrid which, with the false false edge, makes it particularly effective in jab. The bevel is high, allowing for a very effective cutting angle.
The blade is immediately recognizable by the characteristic fenestration, which allows for considerable lightening without compromising its strength. It is made of Böhler N690 steel, with heat treatments that bring its hardness to 58 HRC for the best combination of edge hold and resistance. The finish is satin with flat grinding.
The handle in anodized Anticorodal alloy, compared to the original, has the characteristic lightening on the sides that make the Extrema Ratio knives immediately distinguishable.
The arched shape and lateral “bellies” of the K1 offer excellent grip in both “saber” and “reverse” grip.
The terminal part of the handle curves to form a sort of hook which allows particularly easy and rapid extraction from the scabbard, while the tang protrudes from it with a triangular cusp which acts as a glass breaker with a slot which allows the knife to be equipped of lasso.
The leather scabbard faithfully reproduces the original while maintaining both the qualities of ease and speed of extraction. The carry can take place in an upside-down axillary position, horizontally on the belt or tactically on the thigh. The K1 equipment is completed with a polypropylene case, full leather sheath and underarm shoulder strap.
