Live edge or natural edge is a style of furniture where the carpenter incorporates the natural edge of the wood into the design of the piece. Live edge furniture often incorporates gnarly wood, such as Alligator Juniper, mesquite and salvaged wood that could not be used in conventional woodworking. There are special challenges involved in working with this type of wood, and several methods for live edge have developed. Some leave the natural holes and cracks in the wood while other artist fill them with resins.
George Nakashima, winner of the Institute of Architects' Gold Craftsmanship Medal, is known for leaving the natural edge of the wood as part of the finished piece including in his series for Knoll in 1946. His style is considered an extension of the Arts and Crafts movement and employs craftsmanship that Nakashima said was "not only a creative force, but a moral idea."  Mixing Japanese, American and International Modern style he designed furniture lines for Knoll and Widdicomb-Mueller "using timber organically and deliberately chose boards with knots, burrs and figured grain."
