One of my first throwing knifes

I made this knife out of a old leaf spring that was flatten out on anvil and quenched in vegetable oil , after i put him for a 36 hours in vinegar , that's why stell have this nice black pattern and hamon line on the end of blade . Vinegar is cheap and easy to find so i often use him when i want that nice black pattern on knives or other tools made out of a high carbon stell . Btw vinegar can clean metal from rust and that pattern add some rust resistant for high carbon stell .



I write this post for test to see how it will look on this site .
