Forget the "Spiky" things unless you want to remove a lot of material
from the wheel in a hurry - good for rough work.

Find a diamond "point" type - they are not too expensive. But you gain
a lot of control during the dressing. You can also get a very round
wheel that has as flat of surface as your hand can move sideways
across the rest - my favorite type.

Diamond wheels are dressed with a diamond point (from what I
remember). However, you have to mount the point in a fixture to get
it to work good. When you say you have a couple tool grinders, are
you talking about the hand held things or what? Could you be
referring to a bench grinder of some sort?

I would be surprised if you have a "Tool grinder" as they are usually
specialized type grinders for grinding tools and cutters. I have
never seen one outside a machine shop's tool room.

If you can, send me a picture of your grinder so I can better identify
it.
