After reading several posts and several suggestions I picked up a bottle of the Birchwood Casey Super Blue.

I wiped down the blade with acetone and let it dry. Then I applied the Super Blue with a q-tip. It changed color almost instantly, but was 'spotty'. I rubbed it down with very fine steel wool and applied another coat. I repeated this several times and ended up with an almost black deep blue that looks as good as a new S&W out of the box.

GREAT stuff. Thanks, all, for your constant help and patience.

The knife that worked is made from tool steel.

I tried the blueing on one of my Buck knife blades and, just like it says on the label, it didn't react at all on the stainless.

i have that super blue stuff, glad it works so nice, i'm gonna use it on some m-2 skinners. use 0000 grade steel wool, or bronze wool.
 
I use it on cpm3v after bead blasting. It comes out a really nice gun metal grey. Not very blue at all but I think I like it just as well. It turns mild steel blue with several coats of course. Bruce Bump
 
"Quick blues" are merely patinas. The will wear off very quickly, and lead to blotchy, sometimes flaky looking finishes. I hope the knife is not for a Paying client!
Most carbon steels will professionaly hot blue. NOTHING beats the look of a mirror polished hot blued blade.
Guns are blued this way for a reason. (so are machine screws, tools, etc) The bluing penetrates the surface of the steel and forms a passive oxide coating, not a coloring like a patina.
Hell, if you want to go all out, you can even hot blue Stainless! (special chemical knowledge required)
