At just about an inch in width, the Heavyweight knives are endowed with a slightly heavier tang. The thickness of the blade is still 2.6mm, so aerodynamics are an efficient factor in the design. The double sided blade is factory sharpened, and has an oblong curve. The oblong shape puts enough weight at the front to ensure a forward strike. The two-toned blade style is an awesome touch to the outward appearance, but alas, the shape is truly functional. White designs are painted on the knife. The set of 12 comes with a folding nylon case.
