The Nesmuk Janus office knife features a 9 cm blade made of niobium high-performance steel with a diamond-like carbon coating, designed as a versatile universal cutting tool. This special steel alloy contains niobium, achieving exceptional corrosion resistance while maintaining a consistently fine steel structure, resulting in superior strength, edge retention, and cutting performance. The matte black DLC coating is only a few micrometers thick but offers extreme hardness, resistance to acids, temperatures up to 300 °C, and excellent scratch resistance. The low-friction coating allows for smoother cutting through various materials. With a hardness of approximately 60 HRC, a flat grinding geometry, and fine tip execution, this office knife provides precise cutting ability for preparation and decoration tasks. The handle is made of solid, seamless black Micarta, a high-tech composite known for its impact resistance, durability, and resistance to moisture, acids, and alkalis, making it a preferred choice among professional users. The transition between the blade and handle features a matte brushed stainless steel pin. This model includes a high-quality matte black presentation box with a certificate of authenticity and access to the manufacturer's 30-year sharpening service program. The overall design combines functional precision with durable construction for demanding cutting applications.
