The No. 91 combines the best of the Edward Preston and Sons’ plane designs with modern WoodRiver® features to create a “new classic” with the look and feel of a shiny antique but the body of shoulder plane equipped for serious shopwork, whether cleaning up tenons, rabbets and dadoes or creating joints. The WoodRiver® No. 91 is the result of over two years of extensive prototyping and testing to develop a classic look for a plane that works as good as it looks. The classic shoulder plane features were retained – narrow body, slightly proud blade (to clean corners), sides square to the sole, flat bottom and a necessary robustness—but a major new feature was added, an adjustable toe used to control the throat opening and help to minimize tear-out on end grain. The body of the No. 91 is Cr40 stress-relieved ductile steel, machined square and flat, and the blade is Mn65 tool steel hardened to HRC60-64 which combines toughness with the ability to take a keen edge. The blade advancement mechanism is smooth and precise.
