I have a set of giraffe grips of a Turnbull Ruger Bisley 45LC. Before I bought the revolver I never knew they used giraffe bone. Mine are smooth with nice grain. I like the feel.
I looked at some giraffe bone last week, but I wasn't sure if the bone was thick enough to get a set of grips out of it. I might have to give some a try and see how thick it is.
