Several of my Arno Bernard (Sr) and his son, A.B. Jr, fixed blades have giraffe bone handles. They make them in their homeland, Bethlehem, South Africa, where the material is more easily found. They also use croc hide, sheep horn, mammoth ivory and molars, spalted woods, sambar stag, and even paua abalone for handles. Their knives are still bargains in the semi-custom world and include full length tapered blades of Bohler N690 steel and come with cape buffalo hide sheaths. They range from his "Bush Babies" series, from ~$140 up in size and price. I bought a 'Dassie' with giraffe shinbone handle from A.B. Sr. himself at BLADE 2013. I had met him at the previous BLADE show - super nice folks! BTW, I cut the belt loop off the Dassie - at 5" OAL/2.6" blade, it makes a great pocketable fb - in a cape buffalo sheath.
I've seen 110's in sambar stag, what was supposed to be snakewood, and other woods - giraffe bone would be neat!
