Darkening Stainless Steels

[timogranzotti]

I recently ordered a Predator WSK and was searching for methods of darkening the 440C Stainless Steel blade. I was looking for a method or acid that would be
the least toxic as I will be also using the knife for gutting, skinning, etc. but durable enough for heavy chopping, drawing, etc. Any Ideas? Thanx!

Several folks have reported good results with this kit:

They make another kit for non-stainless.
I cannot speak from personal experience as I do not like darkened blades on my knives.
