Thread: Not quite sure what I've got here

The 'yellow' side is the finishing side. The blue side was considered inferior and only used to reinforce the fragile coticule. In recent years guys have found the blue side might be effective with slurry. Personally I don't bother with the blue ..... A.K.A. bbw or Belgian Blue Whetstone.

The hindustan is not known to be much good with razors. AFAIK they were abundant in Indiana to the point that they were used for tombstones quite a bit. Unless I'm badly mistaken they harvested most of what was around years ago. Might be good for your pocket or kitchen knives. If I'm (shudder) wrong I'm sure someone will be along to correct me.
