Sticks are a type of handle, and can be found through many ways. They can be sharpened to do a bit more damage, but this is not very much, and they are crafted to the same things as the normal stick. Sticks are flammable. While sticks deal only slightly more damage than bones, another type of handle, one can exploit the flammability of sticks to an advantage by creating torches.
