Minimalist handle with an ultra-flat, ergonomic cross-section, covered with non-slip rubber for a secure grip. The blade is made of hardened 401 stainless steel. Durability of performance is ensured not so much by sharpness as by the quality of the material that ensures durability of the edge. Rhomboidal section of the blade for increased resistance to bending and breaking. One side is smooth and the other is partially serrated with line cutters. Can be attached to the calf with rubber straps and buckles or to the belt.
