Cro-magnons increased their food supply by inventing tools. hunters crafted special spears that enabled them to kill game at greater distance. digging sticks helped food gathers pry plants loose at he roots. These expanded tool kits included knives to kill and butcher game, and fish hooks and harpoons to catch fish. A chisel-like cutter was designed to make other tools. Cro-Magnons used bone needles to sew clothes made of animal hides.
