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.
WARNING: This method produced a harmful gas that should not be breathed in. Please use in a well ventilated area.
Step 1: Items Needed
All the items that are needed can be found around the house or for cheap elsewhere.
Blade (steel works best, stainless or carbon)
A pair of alligator clips
Alcohol or Windex
Nail Polish (optional)
Some Artistic Ability
Step 2: Cleaning/Mixing Salt and Water
Take some alcohol or Windex and clean the blade thoroughly. This helps the process go smoother. Also make sure the alligator clips, battery, and all other necessary components are clean and functioning properly.
At this time also mix the salt and water. I find that using one tablespoon of salt per cup of water works pretty well. Warm water makes the salt dissolve quicker. Remember, you don't need much salt water.
