So, my buddy sent me another jadeite sharpening stone he cut. It is an odd shape, but that in no way affects performance, It has two flat faces one of which is missing a corner chunk. On side has been lapped on a DMT plate the other is flat, but has not been lapped. I think if you make a stand for it out of a wedge shaped wooden block it will work great. or glue some rubber feet on it. lol.
the dimensions are:

length: 7.25 inches
width: 2 1/4"-2 3/8"
height low side: 1"-1/2"

Price: $150 conus shipping included
