I'm awaiting two custom Carbon Shaving razors from Sean:
Adamas
This has a chromium-based DLC coating with a jet black color on the Damascus steel. The coating is applied and then hand sanded to reveal the contrast of polished metal with the carbon black coating. Its base plate has an open matrix web structure with 'lightening holes.' The sanded finish is smoother than that of the Damascus model.
Cx-Graphite Titanium
The color of this DLC coating is a shimmering 'grey rainbow' (which can be seen a bit in the last image). The razor's base plate also has the open matrix web structure.
