| ETCHING PROCESS - USE EXTREME CAUTION WHEN USING ACID:
Degrease with acetone
Mix etching Solution:
2 parts ferric chloride
1 part distilled water
Or
60% ferric chloride and 40% white vinegar.
Dip blade in a plastic container containing the acid mixture, let stand for a few minutes and remove to see pattern, rinse blade with warm water and put it back in the acid till the desired depth is achieved in the blade, it could take several minutes to get the depth and contrast you want.
On the last dip remove blade from acid and allow the black oxidation to stay on the blade. Rinse in warm water & baking soda to neutralize the acid. (Windex will work also)
Dry quickly with blow dryer, or some other means, to allow the black oxidation to set, and after it is completely dry, spray with wd-40, tri-flow, Break- Free, or clear paint to seal and protect the blade.
