Chinese Agate *PIC*

David Weaver
The slowest stone that I have. In fact, I don't know that it could finish an edge after a washita and it seems to almost not cut at all. I tried to prepare an edge with a diamond hone and then microbevel off the wire edge from the diamond hone and install a tiny very fine microbevel with this stone. After a few minutes, I couldn't get the entire edge to leave the stone.

The edge in this picture is very fine looking, but don't let it fool you, it took a minute or two of an almost finished edge to get to this point.

This stone is hard but it has almost no sound transferrence (no tink tink like a ceramic or trans arkansas stone), and the feel is extremely soft. You can slurry them and they will cut a little bit for a tiny short period of time (like not even a cycle to hone something and then the rolling particles will make an edge that's not that fine).

If you try to focus on a tiny small area, I've found with this or ark stones, you'll get tiny failures at the edge if you get heavy handed.

The pictures make it look better than it is, there are a couple of failures bigger than that. great for aligning edges, though. I dropped my vial of 1 micron diamonds somewhere and can't find it -the soft feel of this relatively hard stone would make it very pleasant to use with micron diamonds.

These aren't that cheap - $80. There have been a lot of cheaper versions on ali express, but most of those are pressed-together cuttings or stone dust and those don't cut finely and aren't worth having at all. This one is a novelty.

For practical purposes, compared to washita and then linde a (buffer)- notice the uniformity of that system:

Sharpness off of the agate isn't that great (the pictures look nice because I buffed the bevel side to get rid of the wire edge). Sharpness off of this washita and linde A edge is otherworldy for a time commitment of about one minute.

Sharp enough to hang a cherry shaving over the lens of the phone and see this well through it:
