Thread: Agate / Greenstone?

Hi Guys,

I received the green stone a few weeks ago although due to moving into a new house it took a while to do some testing.

The stone is softer then what i was expecting, softer then a Translucent Arkansans but harder then a slate. So lapping was much easier then i was expecting.

I lapped the stone with my DMT lapping plate and I polished the scratches out with a well worn 325dmt. The 325 DMT creates a light slurry only after a 5 or so lapps (As i said, much softer then a translucent Arkansas)

I first tested the stone with water, it almost cuts and may be the better option for this stone although some more testing is required. After testing with water i finished a razor on a 12k Naniwa SS and then moved to the green stone with WD40 on the stone and even WD40 seems to be too thick, the blade feels like it glides over the stone rather then against the hone... It's more like buffing on a piece of glass then honing.

The razor turned out surprisingly smooth, it seemed to have improved the Naniwa 12K and i shaved directly off the stone. No stropping.

I still need to do more testing and probably need to test it on another few more razors before i can conclusively determine its performance.. Although this 'may' be a nice hone for touch-ups.. After more testing ill know for sure.
