Sharpening Supply is selling new Norton Washita stones. The price is right, IIRC less than $40 USD, so I decided to give one a go for no other reason than curiosity. I have no need for more stones but I'm a stone sucker.
Here is a photo of some of my Washita stones:
The new Norton stone is bottom right. To the bottom left is a Norton "Lilly White". The middle stone is a Pike "Lilly White" and the top stone was advertised as a Washita, my guess one of the courser stones.
I had time to put metal to stone tonight. When you reach a certain age sleep isn't easy and sharpening is one of the few thing you can do and not wake the house. As expected from just feeling the stone surface the stone is very fast, my guess somewhere between a coarse India and a med India, It will be interesting to see where it settles in after use. My guess it will be close to a med India.
Anyway it could be a nice stone to add to your kit.
