Roger, I have used whitetail antler since '91, with excellent results. I have used some elk, but the elk has too pourous core for my liking. Almost all my earlier knives included antler,metal spacers,wood, 'glassed. One knife, an Osage Orange,brass shim stock spacers,and two 1/2" whitetail antler spacers laid in the back of a pickup truck bed after field dressing a deer.The knife was left there all fall, winter,spring, in the open bed in the weather. Except for some L6 blade rust, the knife was just fine. It was my first custom sold knife, also. There was no seperation of the handle and the materials were in excellent shape. For further documentation I can furnish the customer's name and contact for you, Roger. Good stuff, whitetail antler (and of course, the Acra Glas).
