Actually, there is a way. All you need is some narrow slices of cheddar cheese and a can of anchovies. Drape them randomly over the spine of the blade. Turn your stove on "broil", put the knife on the top tray and let it cure for about 25min.
The result: insta-tiger-stripe, guaranteed to dazzle your opponent and to give you some emergency calories during those long range recon ops.
Non conformed sources even report a rost inhibiting effect of the so coated blade. At least there where the cheese is.
