Abstract
The present invention provides a symmetric, D-shaped handle for use with coping and similar saws which are generally comprised of a saw blade attached to a U-shaped frame having first and second shanks. The handle is comprised of a perpendicular cross-member mounted between the two shanks of a C-shaped member. The cross-member, which is used for gripping, is maintained substantially perpendicular to the saw blade while the planes of the saw frame shanks remain substantially parallel to the cross-member. At the center point of the C-shaped member is an aperture to allow the D-shaped handle to slide onto the threaded shaft of a standard blade holder. A standard fastener such as a wing nut may then be threadingly engaged with the shaft to attach and tighten the handle onto the shaft and simultaneously tension and align the saw blade between the shanks of the saw frame. In another embodiment, the aperture is slot-shaped to allow the handle to be pivoted into a pistol grip position when the operator desires to make continuous cuts in only one direction. In still yet another embodiment, the aperture in the D-shaped member is shaped and formed to be coupled with a protrusion on the shaft of a standard blade holder of a coping saw, thus preventing the handle from rotating about the shaft of the blade holder during use.
