    Usage notes
    (to shape a vitreous mineral'') In modern usage ''knap is restricted to the specific technique of percussion flaking whereby flakes are removed across an entire face or facet leaving a conchoidal fracture. It is distinguished from the more general verb (chip) and is different from "carve" (removing only part of a face), and "cleave" (breaking along a natural plane). The term is used in archaeology for the production of flaked stone tools and in gunsmithing for the production of gunflints. Knap is rarely used in stonemasonry except to denote fine chipping done with smaller hammers but without the chisel.
