This time we have come up with a bit different approach to handle making - we have made a 3d prototype and then we have used it to make a silicone form for epoxy. We have also 3D printed the ethereum logos that are contained inside the handle.

How to blacken steel (hot oxide):
A mixture of caustic soda (700g), potasium saltpeter (250g) and water (1,2 l)
The temperature of the solution should be kept between 120 - 140 C.
I keep the knife inside for about 30 minutes to get consistent black colour, you can manipulate the time to achieve different results, shorter period should give you dark brown or purple - ish colour.
Be careful - this mixture is highly corrosive!

-Austenizing temperature: 830 C
-Tempering: 180 C
