Thread: What have I found???

Lapped it with 80, 180 and 400 wet and dry. It probably took about 40 mins to get it nice and smooth, so it wasn't ultra hard but it did take a bit of effort. The slurry was a grey color.

I doubt it's an Asagi. It's unusual to not see any skin on the sides or base but anybody's guess just what it is exactly.

I have Thuringian like that, but it also can be Asagi, need close up of the stone to see.
Thuringian they are usually super clean, where Asagi have some black spots or bit variation

Thanks everyone. With your suggestions I looked through the Wiki and thought it looks suspiciously like the Escher picture in the SRP wiki: File:J.G. Escher Sohn Water Razor Hones 1.JPG - Straight Razor Place Wiki

I'd be curious to know the dimensions of the small block Escher the wiki describes to see if it marries up to the home I have.

Btw - I think the yellow is staining (probably from floating around in a fishing boat for years) and not part of the natural colour.

I will be giving it a proper try over the next few days and will report back, but an initial go shows that it cuts very slowly with no noticeable metal in the water film after 20 laps each side. It did seem to polish the edge nicely though when viewed with a 10x loupe. Still more testing to go though.

Thanks for helping - still keen to try and understand the provenance of this nice (if a little beaten) stone.

Just thought I'd add, the dimensions of this stone are exactly 5 inches x 2.5 inches by about 5/8 inch.

Thats a light colored thuri, I had one that looked identical to this. The big scratches and the fresh lapped color are both tell tale signs.

If the slurry is the same color as the stone its not a thuringian, they meaning thuris, generate a white looking slurry.

It does. That one is 5 x 2,5 too, a standard size.

A bit of brown 'skin' (as it is called on Japanese hones) does not disqualify the hone as a Thuringian. I have some fine specimens which have it too. There are few pictures about somewhere on this forum.

I agree with Oldengaerde. It both looks like and sounds like a thuringian, even down to the slurry. That staining on the bottom looks like rust staining from wherever it was stored (tin box?) or laid to roll around. May even be residue from what was honed on it. Doesn't look like a skin much.

Thanks again all.

Neil - I think you're right. I'm pretty confident the staining has come from something introduced to the stone. That side of the stone is a bit oily, and I think it might be fuel, rust, fish guts, or most likely a combination of all of the above. Anyway, I am going to clean the stone up with some soap and a brush and see how it comes out.
