I am in the business of selling mammoth ivory. I want to encourage customers, the public, amateur knife makers to work with less than perfect material. Most cannot afford the high end perfect material! I do not use it myself! I show how I use less costly material to create a very nice affordable end product, saying, "And you can too!" Watch and learn with minimal equipment. Fix cracks fill gaps add strength to fragile materials like 50,000 year old ivory..Link too my Youtube channel   / @wiz-oz
