MAC Coltellerie Microsub 304 diving knife (MC MRS06304.G)

MICROSUB 304, an ultralight, compact diver's knife (back-up) with a black matte coated blade. Manufactured by Italian company MAC Coltellerie. An essential piece of equipment during every diving expedition.

304 (18-8) is an austenitic steel containing at least 18% chromium and 8% nickel, combined with up to 0.08% carbon. It is a non-magnetic steel that cannot be hardened by heat treatment, to obtain greater tensile strength it must be cold worked. A minimum chromium content of 18% provides corrosion and oxidation resistance. The metallurgical characteristics of the alloy are mainly due to its nickel content (8% mm.), which also increases resistance to corrosion caused by the reduction of chemicals Low carbon content (0.08% max.), means less carbide precipitation in the heat affected zone during welding and less susceptibility to intergranular corrosion.

Blade - Dagger profile, 3.8mm thick. Made of polished stainless steel AISI 304 with high corrosion resistance, adapted to long-term contact with water. Hardened steel in the range of 55-56 HRC. Blade coated with scratch resistant non-reflective IDROGLIDER GOLD® Black coating.

Both sides of the blade have a Flat Grind for excellent cutting qualities. One blade is fully Plain, the other Serrated with a few millimeters of smoothness at the tip. Serrated blade used in diving, rescue and survival knives. Unique blade consists of one large and three small alternating teeth so called three-step. This pattern increases cutting edge length by up to 24% over a straight blade. Ideal for aggressive cutting of hard materials, plastics and fibrous materials such as rope and netting.

Handle - sand colored. Covered with non-slip textured ABS plastic facings. Steel rivet pin and ergonomic shape of the facings prevent slipping of the hand during work.

Sheath - made of hard PP polymer with holes for drainage of water, moisture. The holster is equipped with a latch that prevents the knife from slipping out in water. To the scabbard is attached two rubber straps and 2 plastic buckles that allow you to attach the case to the hand, leg or to the vest.
