The Nesmuk Janus office knife is a precision office knife featuring a 9 cm long blade made of niobium high-performance steel and a diamond-like carbon coating (DLC). This special steel alloy, with a high niobium content, achieves exceptional strength, edge retention, and corrosion resistance with a fine steel structure. The matte black DLC coating, just a few micrometers thick, offers extreme hardness, resistance to acids, high temperatures, and scratches, while its low friction coefficient ensures clean cutting of various materials. With a Rockwell hardness of about 60 HRC, a flat grind, and a thin tip, this all-purpose knife is ideal for precise cuts in food preparation, decorative work, and general cutting tasks. The handle is made of solid, seamless grenadilla wood, an African hardwood with extreme density, fine grain, and a smooth surface in dark brown to nearly black coloration with subtle dark purple to black veins. A matte brushed stainless steel spacer elegantly connects the blade and handle. This office knife is presented in a high-quality matte black box with a Nesmuk authenticity certificate. The model reference J5G902013 features a color scheme in brown and silver tones that highlights the premium materials and craftsmanship.
