Thread: Fernsler's Ruby Hone

Found this barber's hone in the wild. Original box, instructions, and near mint hone! Instructions say "For quick cutting results, give a few strokes on bottom of hone, either dry or with lather, finish on top dry".

I can't distinguish between the top and bottom. Both sides appear dull in appearance. Any suggestions here?

I have a 400/1000 grit CKTG lapping plate. I thought about lapping this stone, then another thread indicated this is a bad idea b/c of the composition of the hone. Best to use sandpaper b/c the particulates will clog the lapping plate. Overall the hone is in very good condition, except for some random scratches and surface nicks. So I do need to lap it. Any thoughts on what grit to use?

Finally, I have a Norton 4/8 right now. Research tells me this hone is at least a 10K. So hope I get a keener edge off this....

Anyone have input and experience using this hone? Suggestions are welcome!

Thanks in advance...
