Blade
A blade is that portion of a tool, weapon, or machine with a cutting edge and/or a pointed tip that is designed to cut and/or puncture, stab, slash, chop, slice, thrust, or scrape animate or inanimate surfaces or materials. A blade may be made from a flaking stone, such as flint, metal (usually steel), ceramic, or other material.
