Acidrain's statement that the knife is titanium would certainly give the colors shown.
I've not done much Ti yet, but I've anodized a bit of Niobium for the wifes jewelry projects. The colors range is quite similar to Ti.

I use a solution of about 5 grams of Borax in a quart of water. Almost anything that makes the water conductive, but doesn't harm the metal will do the job. No acids or nasty chemicals required.

Here's a Nb color sample I made earlier this year that shows Color Vs. Volts for niobium
