A natural for carpenters, cabinetmakers, and picture framers, this WoodRiver tool employs the principle of the €œshearing€ cut. The massive blades cut like a razor and leave a glass-smooth finish, so no sanding is required. Trimmer is capable of accuracy to thousandths of an inch, and right or left cuts are made at an angle from 45° - 90°. This is a trimmer and not a €œchopper€ and should be used in conjunction with a miter box. Properly used, this rugged trimmer will maintain its accuracy through a lifetime of use.
