Picked up a Barber Hone from Larry at Whipped Dog. It's a Carborundum 104. Unfortunately I can't seem to find very much info on how to properly prep and use a barber hone.

The way I understand it, it's meant to be a touch-up stone to prevent a completely new hone job.

The thing I don't understand is, how do I prep the stone and how do I use it.

I'm familiar with the process of lapping. I do it on CPUs and Heatsinks/Coldplates for better contact. What I'm not familiar with is what the required materials are for lapping a barber hone.

Beyond that, I would assume it would be the same process as using a finishing hone (3-5 laps).

The other issue is that this thing is tiny, and all the vids I see involve nortons or some other similarly sized hone. This is 3" x 2" max. It's really tiny.

Any help is greatly appreciated.
