So I found a couple hones yesterday. Question is, the orange and white I think is an oil stone (norton?) The combo black probably oil, but the white and the small slate.......
The small slate one came from a ball bearing plant and is supposed to be a fine finisher.http://uploads.tapatalk-cdn.com/2016...8bed51e774.jpghttp://uploads.tapatalk-cdn.com/2016...54c677af62.jpghttp://uploads.tapatalk-cdn.com/2016...1650e4179a.jpg
