When early man crossed the landscape, all he had to work with was what nature provided...wood, stone, bone, shell, etc. He skillfully crafted tools for cutting, chopping, scraping, and drilling from outcroppings of rock. Quality stone was a valuable commodity as it provided the material to make tools for daily survival. This past weekend I was able to finish a series of stone knives, three mahogany obsidian and deer leg bone knives pictured above, in preparation for upcoming historical events. I sell these to support my stone addiction. Living in Nebraska there is not alot of good stone to work with so you end up trading pieces of paper with pictures of presidents on them for nice flints, cherts, and obsidians. There are always better flintknappers and artisans than I but really enjoy demonstrating the living skills of our ancestors....making stone and bone tools, starting fires by"rubbing two sticks together", or launching stone tipped darts with an atlatl. Everyone needs something that gets them excited...wakes them up early, and keeps them up late at night.
