I am a sword and knife enthusiast who always found the little etching on the side of my weapons super cool. I searched the web for several ways to make my own etchings on my weapons. To my dismay, there were few methods that did not contain harsh, dangerous chemicals that I didn't have at that time.Then a little spark of light appeared to me in the form of salt water etching! This method contains a few household items that are readily available and cheap.
