Have only found some instructions for wood, but need to know what grade sandpaper, etc to use for horn.
There are many sites, look on the knife forums and so on.
But on this site I have it seen:
You can either search or register and ask.
There are always a lot of people there who make their own knifes and several of them work with horn too.
Horn can be worked the same way as wood, but it is the same material as your nails, so the 'tools' you use on human nails should work for horn too.
And other than wood, you can shape horn when it has been soaked, so it might be worth searching a site with good info.
Be careful about breathing the dust, some kinds of dust are rather harmful, I am not sure about horn but it is worth checking on it.
