checking out a couple of new style diamond stones resin bonded and vitrified part 1 of 2

so a customer sent me a couple of pretty interesting diamond stone to take a look at. a resin bonded 40 micron {about 450 grit} stone from columbia george stoneworks https://cgsw.us/product/2x6-resin-bon... and a vitrified diamond stone from hk knifeworks https://www.hkknifeworks.com/products... in this video we take a look at the stones under the microscope, sharpen a knife with each, then take the new edges to the rope to see what it tells us about the stones. http://caltoncutlery.com
