(the surface is whet).

I've found it in my city in one of neighbours garden
No clue where it came from...
It has pretty the form you can see on the picture, the front surface needed not much lapping.
It is quite small (8cm x 7cm), think it might still work for 5/8 and smaller blades...

After lapping and burnishing its surface became velvet-smooth and shiny.

As per grit estimation its comming quite close to my Y/G-B Thury, but I've seen some bigger inclusions, not sure what they are doing to the edge. As I was testing it around 2 Years back I've had no magnification possibilities to check. will give it some testing.
