Thanks to all for looking and commenting. This is another basic functional tool.
I'd be interested to know how folks deal with delaminations that are revealed during thinning a horn as it was a pretty large void that I ran into. Would CA glue have penetrated well enough and held allowing me to keep the wall thicker? Also this is a cow horn and it seems less dense than the bison was with 'grain' visible on the surface. I couldn't get the really smooth high gloss surface using steel wool that I did with the bison. I was wondering if that is an accurate observation.
