Abstract: Bench planes of different sizes having interchangeable components and an adjustable frog providing full blade support with a frog foot that extends through the plane body mouth to terminate co-planer or nearly co-planer with the sole. The rear plane handle or tote is captured between and secured soley to tines projecting from the frog that is adjustably secured to alternative sizes of plane bodies in a manner permitting forward and backward adjustment of the frog position without removing the plane blade. Superior lateral blade position control is provided by set screws in the plane body and contacting blade side edges. Adjustments in the blade cutting angle without modifying the angle at which the blade is held by the frog in the plane may be made by forming a front bevel on the front surface of the blade.
