The basic components of a puukko are a hilt and a blade along with a sheath, which can be attached to a belt. The puukko's blade has a single curving edge and a flat back. The flat back allows the user to place a thumb or his other hand on it to concentrate the force. Puukkos are used both as a tool for all kinds of carving, especially to work wood, and to clean the catches of anglers and hunters. Some puukko designs have a slightly upwards or downwards curved point, depending on what purpose the knife has. A hunting puukko's tip is often curved downwards to make skinning and opening the animal easier and less messy. The blade is relatively short, usually about the same length as the handle. Fisherman's puukkos sometimes have a small dovetail on point to ease scraping off the innards of a fish.
