Sure wish I could send pictures, but am still in the "smoke signal" period of communication of life. I have been using stone hafted knives for 60 years and find them to be excellent in the field.
My Opinion: I have a skinning knife made from Piute Agate that I have skinned 6 elk, one Yukon moose, a bear, and a white tail buck with. I carry it in a sheath with a small stone antered knife for cutting and gutting. I carry them in a leather belt scabbard like you would a regular hunting knife. I have never had to sharpen either one. I shape the blades more in the fashion of a drop point skinner rather than an arrowhead blade. Have made many of these knives for friends and have never had a complaint. Obsidian blades are much sharper for just cutting and slicing and make better fish knives. but they require mantaince and are easily broken. They do require careful useage (no prying). If you are going to attend the Classic this year, I would be happy to show you how well my old stone knife works. Joe
