Sword? Machete?

Extrema Ratio has the WAKI BLACK listed on their website under “Machetes”. But after looking at the Waki Black and handling it, you might find it hard to classify.

Extrema Ratio has based the Waki Black on the well-known, traditional Japanese Wakizashi swords. The original Wakizashi was a back-up companion to the Katana sword and both were worn by the Samurai.

The Waki Black is a bold, sleek blade with a strong Japanese influence.


The Waki Black is produced using a high-quality stainless steel made by Bohler [Austria]. The steel has been enriched with chromium, vanadium, molybdenum, and cobalt. Has a lanyard hole on the unsharpened area near the handle. There is a fuller on each side of the blade. (Sometimes called a “blood grove”). Black finish. Will hold an edge and is corrosion resistant.


The Waki Black handle is finely textured to provide you with an excellent anti-slip grip. This slightly textured handle gives you a secure grip with both wet or gloved hands. It ends with a lanyard hole with cord plus a pommel.


A quality Cordura sheath is included to protect the sharp blade and keep it from being accidentally damaged. It can be carried on a belt plus it is MOLLE compatible.
