My sister asked me for an all purpose kitchen knife.
I had 5160 laying around so I decided to use it.
Since I know my sister would never take good care of the blade I couldn't leave it uncoated since it would very easily oxidate.
A friend of mine works at a surface treatment company and they DLC coat a bunch of dental drill bits. I asked him if he could coat a knife in with a small batch of products and he agreed.
I tempered the knife at 190 celcius (375F) to try to optmize harness and edge sharpness.
Take a look and tell me what you think!
I've made my first knife about an year ago. I spent a lot of time making my own tools since its really hard to find good tools in Brazil.
