A skinning knife is a knife used during hunting for preparing the game to be used as food: skinning the animal and cutting up the meat. It is different from the Hunting dagger which was traditionally used to kill wild game.
Skinning knives are traditionally designed for cutting rather than stabbing, and usually have a single sharpened edge. The blade is slightly curved on most models, and some hunting knives may have a blade that has both a curved portion for skinning, and a straight portion for cutting slices of meat. Some blades incorporate a guthook. Most skinning knives have a rounded point as to not damage the skin as it is being removed.
All knives possessing the descriptor noun pair of "skinning knife" give the greatest bonus to skinning. This is followed by the non-weapon worn knives, and finally by light edges in general.
