This new modern knife is made in the traditional natural materials of Obsidian volcanic glass, and Elk antler handle. It measures 8 and 1/4 inches long. This piece was made to showcase the beauty of natural materials and to celebrate the traditional technology of knapping stone for tools. Obsidian knives must be treated differently than steel knives. They can cut hide and fiber, but are not used aggressively to chop or carve wood.
