You are correct. The main difference with the thin steel is that there isn't as much material to absorb heat, so it heats up much faster. The transition from feeling hot to being way too hot happens pretty rapidly.

Thanks HNSB...
This brought to mind something else... Has anyone ever seen a straight razor with some thing in the new "super steel's"? Such as I mentioned like S90V, or ZDP-189?
The edge of your razor is so thin that it will disperse heat incredibly quickly. This means that the amount of energy, heat, passing through the metal is much higher than you can feel by touching it-- it is there, and gone, and the temper ruined long before the rest of the razor is anywhere near 200 degrees...
Basically, you want to handle that razor like it's your only kidney.
Got some sewn 4" wheels from Caswell. They work great on my 3,600 RPM machine. Thanks for everyone's help!
What do you guys think about this grinder from Harbor Freight? After looking at the manual (linked to the product page), the RPMs go from 0-10,000. I called HF, and they will sell it for $32, plus about $8 shipping. Follow the link here:
Bench Grinder with Flex Shaft
My only assumption is that he is only going to use the flex shaft--like a dremel. Hopefully he does not intend to use the grinder wheels.
If you have dedicated wheels for each grit (optimal I feel and just JMO)Spray the wheel with WD 40 (lightly)Apply the compound,over a little time it will become impregnated.messy at first but works for me.
