Can't see any real reason why it should. Heat doesn't affect shape until you get to the melting point, and then it'll just get very blunt! Putting it under a pyramid won't work, either, no matter what a lot of web sites and books say. If it's an old-fashioned cut-throat one, strop it. If not, just get another one.

isn't it true you are suppose to run cold water over the razor so it doesn't give you razor burn? a cleaner shave?

Don't use hot water to rinse off your blades when you are shaving. Heat makes metal expand and warp. Use Cold water and your blades will contract a bit making the blade tighter and sharper.
Through many years of experience shaving men with a cut-throat, I was always taught to run the blade under warm to hottish water prior to applying the blade to the skin.
(The face and neck area should also be pre-warmed with hot towels before the application of the lather as this 'pre-softening' of the hair follicle aids in the attempt for a perfect, clean shave.)
