My invention is the bow and arrow. I do archery as a free time thing. Archery actually hurts sometimes, if you do not have the proper equipment, like a wristguard, the arrow will cut your wrist vein, witch hurts really bad. A bow and arrow was invented 64,000 years ago, usually people from india, asia, and austarlia used bows at that time. I use bow and arrows for hunting and for fun. It is also a medevil weapon that knights did not use. The regular soldiers used the bow. Some knights did, but rarely.
