For your lifetime carry.
Includes the Mechanical Pen, Key Cache and 100ml Hip Flask. Personalised everyday essentials with a tungsten carbide surface that's 9x harder than stainless steel, 3.5x harder than titanium and offers incredibly low friction. The finish is applied using a technology, usually reserved for luxury watches and military-grade tools, where nano layers of tungsten carbide carbon are deposited onto the stainless steel surface. As a result, our Black Steel Collector's Set will be scratch resistant to virtually anything you will put in your pocket and the parts should never need to be maintained, let alone replaced.

Considerations: Black Steel retains all the precision and corrosion-resistant qualities of stainless steel, while the tungsten carbide finish increases the surface hardness 9x. Any marks it picks up from regular use should be easily wiped away. However, the surface is scratch resistant, not scratch proof. Anything harder than the surface (diamond, some ceramics) or really aggressive use will be able to scratch it, which is why we recommend keeping it in its cotton sleeve when not in use, and carrying your diamonds in another pocket.
