Easy Acid Etching

Ever wanted to etch your knife?
Well here I show you how to do it

The things you need are:
-vinegar you can use any kind
-sea salt
-2 alligator clips
-9v batery
-razor blade
-cotton swab
-electrical tape
-a small container to hold the vinegar and salt

Add the vinegar to the small container then put a bit of sea salt in it and stir until most of it is disolved.

Take a small piece of electrical tape and cut out the design that you want to etch and then apply it to the piece you want to etch.

Its very easy just connect the - from the battery to the piece you wanna etch using a alligator clip, and the +from the battery to a cotton swab using another alligator clip.

First dip the cotton swab connected to the battery in the vinegar and salt. Then just put the swab on your stencil and keep it there until you get the desired effect. You may see some bubbles and smoke but that's normal.

If you have done everything correctly it should come out pretty good. But if it didnt work your battery may be dead. If it still doesnt work when you have a new battery use 2.
