Hi, I've always been a coticule user as far as naturals go, in the last months I purchased some other miscellaneous stones at my local flea market or in a trade - would love to know if anyone recognizes one or more!


- the top stone is yellow/brown/green and quite soft, generates plenty of slurry like a coti and sharpens very well.

- the middle stone is dark grey, generates little slurry but does a good job, more at the finishing end perhaps.

- the bottom one, which I got in a trade, is pale grey and is the hardest and generates very little slurry. Seems hardly to work with water but I had great results as a finisher used dry.

And here is a side view FWIW:



Thanks guys!
