A doorstopper and a chisel are examples of single wedges. Another example of a double wedge, much thinner than an ax, is a knife. All knives are wedges, as nails, because of their ability to cut or split, and in the case of the nail, to hold something together. The longer and sharper a wedge is, the less effort it will take for.
