Abstract: A hand saw including an ergonomically constructed saw blade holder with a pistol type grip, an elongated support having a blade channel for receiving and supporting a particular “T” blade, and various tooth configurations of a saw blade having a cooperating T-shaped blade shanks. Each blade shank includes an aperture at its rear end for receiving a locking pin positioned at the back end of the blade holder that drops into position to secure the blade within the channel of the grip. Additionally, a trigger-like mechanism on the pistol grip, when squeezed, rotates a rubber surfaced pad upward through an opening in the base of the support to contact the underside of the blade shank pushing it upward into the top of the channel to insure blade stability. The “T” design of the blade allows orienting the cutting surface of the blades in different directions so that a user does not have to twist their body or arm to saw.
