Crossbow bolts (sometimes called ‘quarrels’) are a specific form of arrowhead, with a socketed shaft and relatively narrow, piercing blade. They can have a variety of cross-sections, generally square, but also triangular and other shapes. Few examples are recorded by the PAS as they are made of iron; many are known archaeologically from castle sites, such as Baile Hill, York (Addyman and Priestley 1977, 138; fig. 10). Indeed, there is currently only one spanning hook on the database; there is one crossbow nut in bone or antler.
