"use up" a diamond wheel in your lifetime by grinding steel on it.

for about $160, which would be way more precise than doing it by hand.

If you use a diamond wheel on steel, you will rapidly loose the sharp
edges that do the cutting. So do whatever you like, but you are not
going to convince me to use a diamond wheel on steel when there are
cheaper wheels that work better on steel.

The Harbor Freight grinder may be more precise, but most of the
grinding instructions I have seen have wide tolerances for things as
rake. And a plain bench grinder can be used to grind concave and
convex form tools as well as sharpen drill bits.
