With a surface 3.5 times harder than titanium, the Wingback Black Steel series is scratch resistant to virtually anything and looks handsome in your everyday carry.
Black Steel has a sub-metallic lustre that reveals a glimmer of the steel beneath the surface. It’s applied using a technology called magnetron sputtering, where nano layers of tungsten carbide carbon are deposited onto the stainless steel surface.
The resulting 3um thick finish has a Vickers hardness of 1200 VPN, 9x harder than stainless steel and 3.5x harder than titanium. Low friction ensures the sliding surfaces of the mechanism are satisfyingly smooth. As a result, the Black Steel Collection will be scratch resistant to virtually anything you will put in your pocket.
