Hey hey John!
Odor? I don't recall ever hearing of an odor from Ram's horn..........it was his breath that was bad :barf:
I hadn't taken a sniff-test but I don't notice any odor whatsoever. The first exposure I had to the material was a set of custom grips for a pistola. They were inner horn and I did not notice any strange waif in the air. The RH Vanguard is of the outter or surface horn, at least mine is, and again no odor

.........but I do smoke

Perhaps working and shaping the material gives of an unpleasant aroma

Now, I have heard that working and sanding the coal-black type of ebony can be lethal when the dust is inhaled. I learned that after the fact
