Thread: What type of stone do I have?

Hi everyone,
I am fairly new to using a straight razor. My dad recently inherited and gave me a sharpening stone but neitjer ofnus knows anything about it. This seems like a great community to get answers. I have provided pics

Cant help you with the stone, but i will say welcome to SRP.

Welcome aboard!
The stone could be a man made or natural. The end break could tell us more. Photos of the end, side, and top with slurry would help. It does look as though it was a water stone.as it is not oily.

To make a quick assessment of any stone, I have used the fingernail test:
Run the fingernail across the surface as though you were trying to scratch it.
If it feels smooth to the scraping, it may be a candidate for further exploration.
Again, Welcome to the Forum!

It looks like a silicon carbide dual grit to me. Looking at the break depicted at the top of the first picture, I'm pretty sure I see the delineation between the two grit sections. The conchoidal chip and grain structure where it's chipped seem to bear that out as well.

Today I learned what conchoidal means...
