I did a few Searches and came up with nothing. Found threads on ivory, bone, and wood with collarless pins but no horn.

any thoughts, ideas or experience with horn? I figure it can be done but what is the long term effectiveness of the pins. Will the horn split as it contracts and expands, will it cup?

I have some nice black horn with white streaks I want to use stainless pins on.

i can't see any reason not to except that no one has talked about it which makes me wonder why.
