Extrema Ratio KS Machete

There’s a reason the the Extrema Ratio KS Machete is an instant classic.

Made famous by the Gurkha regiments serving with the British Army, the kukri is a Nepalese all-purpose blade with origins in ancient Greek sickle-shaped swords. Ultimately, this is a machete with a top-heavy, forward-positioned cutting edge, which enables it to function as an axe while retaining the versatility of a long blade.

Extrema Ratio has developed this tool by blending ancient and modern design concepts. The KS Machete employs combination grinds. The razor-like hollow grind closer to the grip yields a fine, sharp edge without compromising the overall thickness of the back of the blade (which needs to be extremly strong).

The tip portion of the blade is flat ground, well-angled to effortlessly penetrate wood and vegetation. While similar tools are usually made from softer steel alloys for elasticity and ease of honing, Extrema Ratio were able to achieve elasticity using hard BÖHLER N690 steel, making for a remarkably durable edge.
