Thread: Agate / Greenstone?

There is a type of Jade used in Asia and this country more as a final finish honing / burnishing than sharpening on surgical and dental tools.

I had one the size of a barber hone that was colored like a Nephrite jade in looks and it was a very final finisher for carving tools.

The one I'm looking at is 200/50/12mm, in contrast to the much smaller ones you see all over ebay. Do you think it has any value as a razor hone? Something to use after finishing for a final polish, or perhaps light touch-ups?

We have greenstone down here, called Pounamu, and many types. I know it is super hard, it is machined with diamond tools, but i have thought it may be ok to hone on, worth a shot anyway. It would be near impossible to lap flat though, that would be the first thing i would ask about the hone you are considering. I would like to know if you have any luck with the greenstone.

If I decide to take the dive I'll let you know how it goes. I hadn't thought about how to keep it flat though. That's definitely something to think about.

It's impossible to tell based on a description and photo, as there are all kinds of green stones with all kinds of properties that look like a lot like that - try asking someone who's been sold soapstone as jade, for example.

Your only hope really is that someone here will have tried that same stone from that same seller, otherwise you could be the one to tell us if it's any good

I ordered one the day the link was posted. Will let you guys know what's it's like when I get it...

I think I have an addiction...

Eager to hear feedback, and hoping it works out for you.

Probably not the smartest decision but I'll let you know soon.

I have a small 3k synthetic ruby stone. I use it to shape heels and toes so I don't gouge up my good stones, it works very well for this. It is very hard and decently fast. It would be very difficult to lap, however. Diamond would be the only thing that would touch it and it would ruin a diamond plate.
