mindphlux posted:anyone know what in knife manufacturing might cause that kind of rainbow effect if subjected to heat? it seems sort of permanent - but not really like a residue, like when the bottom of a pan gets discolored because you burn oil onto it - it's more like the metal itself has gone rainbow. That's surface oxidation, it happens when you heat up mild steel. Sounds like they just knocked knives out of whatever scrap was the cheapest at the time.

mindphlux posted:Is it really? Why would one knife do it, and the other knife not do it? just different batches of steel? It really smelt like some chemical residue burning off the knife, and the otherone didn't have the same smell/wisps of smoke coming off... Pretty much, different carbon content and/or alloys can keep it from happening until much higher temperatures. As for the smell and smoke it's entirely possible there was some residue from machining or some type of lacquer or clear coat on it.
