Yes, it would be impossible to stamp heat treated blade without re-heating the metal. I think it's technically possible to apply / direct heat to a small local area of the blade and stamp it without affecting the structure of the blade as a whole. It'd be a delicate procedure (and the stamp tool itself had to be hardened !!!), so I agree - it had been likely done when the blade was made.
