Joiner: A maker of furniture before the days of the cabinetmaker (who came into his own at the end of the seventeenth century). Originally known as an Arkwright, there is a reference to ‘the joiners’ of the City of London’ as early as the 1400. The joiner did in fact join pieces of wood together by means of mortise and tenon, dowels or wood pins, whereas the cabinetmaker was to bring with him a new technique which involved the use of different joins and metal fasteners such as nails, screws and also glue.
