I just finished polishing on old 5/8 Wade&Butcher with my Dremel and it looks great! However, even after going through the honing and pasted strop process, it doesn't seem to shave like it used to even after thorough stropping. It very well could be my imagination, but is it possible to ruin a blade's temper by polishing using a rotary tool (circa 2500 RPM) such as a Dremel? I noticed there was a substantial amount of heat generated in the process, with the blade a bit too hot to touch at times.

Any ideas?

Thanks in advance!
