Hey folks, I just gave my first try at etching some 5160, ball bearing, nickel Damascus. I mixed 2qts of distilled vinegar with 15 oz of lemon juice and a 5lb bag of table salt. I mixed it together and got it to a slow boil, and after about 20 minuets I wiped the blade down with acetone and submerged it into the simmering concoction.
After about 8 minuets I took it out and washed it off with water and detergent, and then covered it in oil. I think it turned out pretty good
, I am saving the mixture to use at a later date.
