A dual reciprocating blade landscape saw is operably connected to a rotatable shaft of an input device. The landscape saw includes a worm assembly having a lower housing and a worm disposed therein, the worm operably connected to the rotatable shaft of the input device and having a spiral thread, a worm gear assembly having an upper housing and a worm gear disposed therein, the worm gear having a disk comprising a cutout and a plurality of outer teeth engaged with the spiral thread of the worm, and a pair of blades coupled to opposing sides of the worm gear. The rotatable shaft of the input device drives the worm of the worm assembly. Rotational motion of the worm transfers to the worm gear to permit the pair of blades coupled thereon to move linearly in a reciprocating sequence.

Dual reciprocating blade landscape saw with enhanced durability and performance

The device is based on using a thrust bolt in a modified C-clamp design to push a pressure plate to pry apart two intersecting flanges of a profile. The device is primarily used for on-boat repairing of aluminum extrusion profile boat toe rails that have segments of their vertical flanges crushed inward. It has utility for bending any flanges apart that are greater than 20 and less than 160 degrees apart to start with. It has utility for bending flanges apart that are made from any material, such as metal, that has an elastic limit and enough plastic flow to permanently bend without rupture.
