Abstract
An open-ended handle is disclosed for use with framed saws, such as coping saws. The open-ended handle is generally J-shaped and has a grip member that is perpendicular to the saw blade. The open-ended handle is mounted to the saw such that the grip member is also symmetrical about the mounting point. The present invention provides an arrangement in which the hand-grip portion of the handle is symmetrical about a longitudinal axis of motion when the saw is in use to allow the greatest amount of power to be transferred to the saw blade along a single line of force which not only provides for accurate cutting, but also eases tension on the user's hand and wrist to reduce fatigue. This arrangement provides a saw that is equally balanced and usable in both an upright position and an inverted position for accurate and easy cutting in a downward direction as well as an upward direction. While holding a piece of work in one hand and the saw in another, a user can easily cut the work downward, flip the saw in a single motion to an inverted position, and finish the cut in an upward direction.
