The original of this model is the model with minor changes of the HIGO X. In this model’s handle Rockstead used carbon fiber with the titanium. The handle has two types of titanium coloring - the blue (BL) color and the silver gold color (SG).
This knife’s ZDP189 blade can cut Manila rope about 1,000 times, and still slices through paper cleanly. This knife has a blade angle of 30 degrees near the half, and 24 degrees near the top with one continues, gradually reducing angle connecting them. This reducing blade angle is a product of Rockstead's continueing pursuit of superior sharpness.
