Is aoudad horn a good choice for knife scales?

I was rummaging through some boxes in the garage and found some ewe horns from years ago.

They feel 'grippy' enough to make sense, but I don't kn ow if they are workable or stable enough.

Yes, they make a great handle. The only thing I would do is stabilized them. I actually have a few pair of rams horns curing in my oven right now.
