i picked up this barber hone at the flea market for $1.00 this last weekend.
it was heavily cupped in the middle on both sides. I managed to flatten one side on my sidewalk, then a little honing with wet sandpaper.

can anyone half way identify it? I am trying to figure out if it would be a good finishing stone to use after my Norton 4k/8k or would the 8k norton be better to use last.
