Produced in Olean, NY, in collaboration with the skilled people at KA-BAR knives, the Spartan-Harsey Kukri knife has been designed to be a highly durable hiking knife. The kukri features a blade of over 22cm, making it an all-around tool due to its center of mass, allowing the user to slice while cutting to even penetrate thick objects.

While this blade is primarily famous for its military use, the kukri is more commonly employed as a multi-purpose tool in fields and homes across Nepal. Its uses range from construction, clearing, cutting firewood, digging, butchering animals for food, slicing meat and vegetables, skinning animals, to opening cans.

It can function as a smaller knife using the narrower part of the blade closer to the handle. The heavier and wider end of the blade, towards the tip, functions as a hatchet or a small shovel.

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 Master.

Based on the well-known MK-9, designer Dietmar Pohl has developed the new Tactical Nine. Reduced in weight and more compact in size, the Tactical Nine Black is still a full-fledged knife.

The sturdy 20cm long and 6mm thick spear point blade is suitable for a wide range of applications. For high edge retention and blade resilience, the choice fell on the well-known D2 tool steel.

The stonewashed finish creates a scratch-resistant surface and also increases the blade's resistance to corrosion. The step-shaped grip design offers an excellent and secure grip. For powerful or delicate work, the pronounced and also rounded finger recess in front of the guard allows the knife to lean forward. A hidden hole in the end of the handle offers the possibility to mount a lanyard (included).

The Kydex sheath of the Tactical Nine Black has a material thickness of 2.5mm which provides the basis for a well thought out and durable carrying system which fully meets the high demands placed in practice on a tactical knife. A leg strap, infinitely adjustable in size, with snap closure allows it to be fixed to the thigh of the wearer.

Basato sul noto MK-9, il designer Dietmar Pohl ha sviluppato il nuovo Tactical Nine. Ridotto nel peso e più compatto nelle dimensioni, il Tactical Nine è comunque un coltello a tutti gli effetti.

La robusta lama spear point lunga 20 centimetri e spessa 6 millimetri è adatta per un'ampia gamma di applicazioni. Per un'elevata ritenzione del filo e resilienza della lama, la scelta è ricaduta sul noto acciaio per utensili D2.

La finitura stonewashed crea una superficie antigraffio e aumenta anche la resistenza della lama alla corrosione. Il design delle guancette a forma di gradino offorno una presa eccellente e sicura. Per lavori potenti o delicati, l'incavo delle dita pronunciato e anche arrotondato davanti alla protezione consente al coltello di protendersi in avanti. Un foro nascosto all'estremità della maniglia offre la possibilità di montare un cordino (incluso).

Il fodero in Kydex del Tactical Nine ha uno spessore del materiale di 2,5 millimetri che fornisce la base per un sistema di trasporto ben congegnato e resistente e che soddisfa pienamente le elevate esigenze poste in pratica su un coltello tattico. Un cosciale, regolabile all'infinito nelle dimensioni, con chiusura a scatto consente di fissarlo alla coscia di chi lo indossa.
