Katla, designed by Jesper Voxnaes, is a liner lock folding knife, which brings back the Tanto profile blade with a bevel that enhances the excellent cutting qualities.

The rotation mechanism is provided by thrust bearings, and it can be opened with either the double thumb stud or the very fast flipper.

The detail that characterizes the Katla is the 3D processing of the handle at both ends of the bolster, which reinterprets in a modern way, the inlays of the classic Viper models.

The flat edges and the titanium clip allow for comfortable and discreet carry.

WAKI XXV ANNIVERSARIUM LIMITED EDITION is a limited series version of only 150 pieces that keeps all the features of the famous Waki model intact.

This product is an elaboration of the Japanese Wakizashi sword, a typical blade 30 to 60 centimeters long, which the Samurai always carried in contact with the body, where the Katana was carried exclusively in battle.

The blade has the classic Japanese Tanto profile and is made of Böhler N690 steel with heat treatments that raise its hardness to 58 HRC for the best combination of edge hold and strength. The blade, with flat rounding, features a precious satin finish.

The handle, in black coloring, is made of Forprene while The black-colored Cordura sheath is equipped with a MOLLE system that ensures safe carrying of the razor-sharp blade by protecting it from shocks that could reduce its efficiency.

Takeshi Saji was born in 1948 in Takefu (Fukui prefecture), a city located roughly in the center of Japan and in the heart of an area for centuries devoted to the production of blades. His workshop is still there, built around the oven thanks to which, for several years now, Takeshi Saji has been forging steel (especially damascus) with which he makes various models of traditional Japanese knives. The choice of materials for the finishes (mainly natural), the essential lines - evocative of use - and the chromatic combinations of rare impact make his creations unique and unmistakable in the panorama of world cutlery and, at home, they have earned him the prestigious title of Maestro.
