Brushed black zirconium knife scales (knife handles) for benchmade 940 osborne – signature folding knife. Scales: 67gr without the knife. Installed with knife: 120gr. Use hardware from factory knife. Pure zirconium (atomic number 40) is a lustrous, grey-white, very strong, lightweight and hypoallergenic metal that closely resembles hafnium and, to a lesser extent, titanium. Zirconium is extremely resistant to heat and corrosion and it is lighter than steel. Through my own heating process, i create a unique appearance, that’s called black zirconium, dark-green and black rainbow. Through this high heat, a layer of extremely hard dark oxide grows on the metal. This thin layer is much harder than pure zirconium, which does not rub off over time from your spinning top. Therefore, it is more durable than black-coated items, such as black tungsten and titanium. This color is permanent, it does not fade, tarnish, or change color.
