This was quite a project. I started with a piece of deer horn, which I drilled and turned round on my lathe. I then just about destroyed it altogether by breaking it into pieces with a sharp chisel and a hammer. Several of these pieces were then thrown away, and I filled in the gaps with lapis lazuli and sterling silver. The trim on the pen is plated with platinum. The writing tip is ceramic, making it a pleasure to sign your name with.
This one was difficult to give up, but it is now sold and part of a private collection.
