Great for a machine shop
This is exactly what I needed for cleaning up the surface of my milling machines. The stone has dual grit, which isn't really that useful, but I suppose the rough side could be used for larger burrs and oopsies on the mill. The fine side is perfect for finding and smoothing down the mill table. It's also useful for cleaning up the bottom of Kurt vices and any other part of a machine tool that should be flat.

It is a real Norton's stone.
I saw a few reviews saying questioning its authenticity of being a Nortons product. I can confirm it is a real Norton's stone. I was a little nervous since seeing the reviews myself but still took and chance. Using this for my mill and CNC

Fits well in the hand.
I use these to stone the burr on my CNC. I like the groove, it’s easy to hold. The size is perfect to manipulate. I use the fine side the most but it’s nice having a course side Incase a burr is particularly nasty. Norton is the Bomb.

Blanchard surface stone.
Perfect for work on grinding tables. Removes burrs and high spots with coarse or smooth surfaces. Works best on Blanchard magnetic table surfaces. Long lasting as well. Fits in your hand with ease.

Exactly what it is.
Does exactly what it should do. I've stoned surfaces, I've knocked off burrs, I've even sharpened knives. It works.
