The Extrema Ratio T4000 C is a fixed tanto knife. Specially designed for fans of the Japanese tanto shape, but with modern influences as well. It features Extrema Ratio's characteristic stylised forprene handle and a tactical MOLLE sheath.
The striking thing about the T4000C is the ratio of blade height to blade length. Because the blade is relatively short, you have a very “stubby” knife. It's compact and robust in hand. The tang is 6 mm thick. It is pretty sturdy, and hefty enough to feel reliable in hand. Just in front of the handle, towards the tip, the blade is 3.8 mm thinner. The fuller (groove) in the sides of the blade makes the knife lighter, without weakening the thickness and firmness on the spine.
You can carry the Extrema Ratio T4000 C in a compact, lightweight MOLLE sheath.
