The Obsidian bushcraft knife has an overall length of 78 cm (30.71 inches), a blade length of 54 cm (21.26 inches), and a net weight of 1000 g (35.27 ounces). This knife's blade has a tapered spine thickness from 0.6 cm to 0.4 cm (0.24 to 0.16 inches) and an edge hardness of 60 HRC.
This knife's blade is made from Daido DC53 steel, a high-carbon cold work steel alloy containing approximately 1.0% carbon, 8.0% chromium, 2.0% molybdenum, and 0.3% vanadium, which provides excellent toughness, wear resistance, and high hardness. This knife's blade undergoes a differential heat treatment process by selectively hardening the cutting edge while keeping the spine softer to increase overall toughness and reduce brittleness. This is achieved by edge quenching, where only the edge is rapidly cooled in a quenching medium, followed by tempering stages to achieve the desired hardness and structural integrity.
This knife's blade has a diamond-like carbon coating applied via physical vapor deposition (PVD), where carbon is vaporized in a vacuum chamber and deposited as a thin film on the blade surface, forming a hard, low-friction layer with sp3 and sp2 bonded carbon structures that enhances wear resistance, reduces friction, and provides corrosion protection.
This knife's handle is constructed from G10, a composite material formed by stacking layers of fiberglass cloth impregnated with epoxy resin, then compressing them under high pressure and heat to create a durable, lightweight laminate with high strength-to-weight ratio, resistance to water and chemicals, and non-slip properties in various conditions.
This knife's tsuba (guard) is made from aviation-grade 7075 aluminum alloy, which primarily consists of zinc as the main alloying element, offering high tensile strength (up to 572 MPa), toughness, and fatigue resistance. This alloy is heat-treated with T6 temper for enhanced mechanical properties, providing strength with minimal weight.
This knife's sheath is constructed from carbon fiber composite material formed by stacking layers of carbon fiber cloth impregnated with epoxy resin, then compressing them under high pressure and heat to create a durable, lightweight sheath with high strength-to-weight ratio and resistance to impact.
