Blueing

[ohioguyUSAF]

are the bottles of blueing worth buying and can you blue 440c?

They work okay on clean gun steel but I don't know about 440C. Here is an outfit that can probably help you out with your question.

If they can't, this one probably can.

There may be better forms of colored coatings available than bluing.

The bottles of bluing are really designed for touch-up not to do large surfaces and they won't work on stainless steel....Do a search you'll find the info for various coatings that work on blades.

You can't blue stainless, (blueing is a stain)

I have a good method to get a good blue job with the cold blue on carbon steel.

Rub the steel out to a 400 grit or finer. Clean with soap and water and then clean with alcohol. Dry the steel, apply the cold blue liquid. work it liquid around the blade with the dauber. This will be splochy. Rinse the blade with water. Dry with clean paper towel. Now rub with dry 0000 steel wool. (This will remove some of the blue.) Re apply the cold blue liquid. Repeat this 5 or 6 times and it will result in a rich deep glossy blue with no streaks or sploches.
