Knap
English
Verb
knap
- To shape a hard, brittle material (usually flint or obsidian ) by breaking away sections, often forming a sharp edge or point. Distinguished from "carve" by the fact that each fracture goes through the entire work piece, and from "cleave" by curved or conchoid fractures (due to the work piece not being a single crystal).
