1. Find a rock to use to make a knife. It has to be a sharp rock. Flint is a one of best materials that will do.
2. Get a chipping tool. You want something hard, light, and easy to hold. Bone is a best material for this.
3. Get a flaking tool. You want something that is fairly sharp and can be used to flake off pieces of knife, so it has to be hard and sharp.
4. Chip your knife rock into a shape you want. Hold the sharp edge facing to the side and using small blows, make it roughly knife-shaped.
5. After you sharpen your knife, hold your flake rock roughly parallel to the blade and press it against the edge of the blade. Flake it until it's sharp.
6.Rub something slightly rough along the edge to hone it to a fine edge. I suggest you to use your chipping rock to do this.
