NORRIS was established in 1860 and made the world's finest planes until the 1950s. Considered the Rolls Royce of hand planes, a phrase coined in a Fine Woodworking Magazine article in the 1980s. In its day a Norris plane cost 4 times that of a comparable Stanley. The Norris has a much thicker iron and cap iron. It is a heavier plane. Also, the iron sits on wood as opposed to metal. All of these things prevent chatter and create a smoother cut. In 1913 Norris patented his famous adjuster which provides micrometer-like, smooth blade adjustment. In 1922 he patented an improvement to this adjuster. This adjuster allowed Norris to outdistance his product from his competitors. It is still copied today.
