cinder block

I want to see you flatten that stone too! Good video, you and Murray Carter - but he cheats by stropping on cardboard after the cinderblock...

To be fair, his stone was a lot more rough it looks like.

Brother we really need to find you a second hobby. Ever tried hunting? Fast cars maybe? Just two of my personal favorites, its a start

How about S&W wheelguns? BTW where do you get pants with pockets big enough to carry that?

If I am reading you right, it would be the "hard" firebrick - the stuff with a high chromium content and actually looks like a tanish brick.

The ones we used in the boilers at the company I worked for made pretty decent stones as long as they were smooth. Used bricks were nicer, I feel, though.

If you took a pair of unused firebricks and rubbed them together, it would refine the surface of both and make them smoother, right? This is a fun thing to have up the sleeve when away from home.
