Makes a noticible difference in performance and looks much neater, no

I'm glad a grinder works for you. Metal files work best for me and I
don't turn the blade edges blue.

I use a 4" angle grinder. Used carefully, no blue.

I used a 6" bench grinder, and no blue either. I run a couple of passes
on one side, then flip it over and do the other side. I don't "dwell" a
long time, as it only takes maybe one second for a pass, taking a light
grind.

Doing it this way keeps the blade cool enough for me to touch it with my
hands.

Belt sander works well too
