Some arrowheads I made

One of my earlier hobbies that I'm not really into so much these days was knapping (flintknapping), the process of producing arrowheads in the style of many prehistoric people by chipping away at stone (I would cheat by using a copper tool, which is easier than stone and antler tools). Here are a few of my favorites that I've done. The largest is about 2.5 inches.

Top row (Left to right): White glass, green goldstone (a form of glittering glass), and flint
Bottom row: Obsidian (this was my first and is the crudest of the bunch), orange fiberoptic glass, agate, blue fiberoptic glass, flint
