I sanded to 400 grit before heat treating based on the idea that I thought it would be easier to sand metal that was not hardened.

I usually take mine to 320 before HT, I used to go higher, but I always had to drop back down below 320 anyways, so I didn't waste paper. Also when I hand sand I really like using tap magic(cutting oil) it really speads up the process and makes great lines.

As far as getting the crud off I quench the blade in oil then let it cool at least until just slightly warm to allow conversion to martensite to complete and then scrub with a brass brush and detergent before sticking it in the oven. It helps not to bake the crud onto the blade.

you like wd-40 better than oil or water? why?
