I mentioned the hardness of their bones in an article years ago, which eventually became a chapter in a book. Can't remember where I found the info, but as I recall somebody had tested pronghorn bones and found them around 9 times harder than domestic cattle bones.
They sure can be tough little critters when hit wrong!
I had heard this too possibly from you. But I saved some leg bones for knife handles and can say for sure it is tougher than cow or deer and a lot like camel which is popular for custom knife grips. So if you want a local replacement for camel bone Antelope is it. It is almost like Ivory maybe less porous.
