A hacksaw blade may include a first end having a first mounting orifice, a second end having a second mounting orifice, a first side face extending from the first end to the second end, and a second side face, opposite the first side face and extending from the first end to the second end. The blade may further include a top edge extending from the first end to the second end between the first and second side faces, a cutting edge disposed opposite the top edge and including cutting teeth disposed thereon, and a tension focusing slot disposed between the first end and the second end, and spaced apart from each of the top edge and the cutting edge. The slot may be formed by material removal from at least the first side face.

A hacksaw with an improved mechanism for applying and adjusting the tension on a blade mounted to a blade mount on a front arm and a blade mount on a rocker arm. The rocker arm is pivotally coupled to a handle and is spring biased to place an initial tension on a blade held by the rocker arm and the front arm. A rotatably mounted lever is positioned on the handle for vertically displacing a nut captured in the rocker arm to pivot the rocker arm and adjust the tension on the rocker arm-held blade. An elongate top frame bar of the hacksaw defines a hollow I-beam cross-section accessible from the face of the front handle and is capable of storing saw blades. A bale screw is positioned in the front member for securing the blades in a position extending past the front handle.

A collapsible or folding saw is provided as a compact hand tool that when folded covers and protects the blade. The folding saw is movable between an extended useable condition and a folded condition. The saw comprises a frame having a longitudinal telescoping upper member, and first and second collapsible side supports depending from the upper member. A blade is coupled between the first and second collapsible side supports, whereby a tensioning mechanism is provided to tension the blade. Further, a handle is provided having a first portion pivotably coupled to the frame and wherein the handle pivots between a first condition to form a free-end handle and a second handle condition where the handle engages the upper member and encapsulates the blade.

A hacksaw multitool is provided. The device includes an elongated body having a first end opposite a second end. A bit receptacle is disposed within the first end. A plurality of interchangeable bits is removably securable within the bit receptacle. A channel is disposed within an upper side of the elongated body, wherein an arm is pivotally affixed within the channel at a proximal end of the arm. A saw blade is pivotally affixed to a distal end of the arm, wherein the saw blade is slidably engaged with the channel. The saw blade is selectively movable between a deployed position and a stowed position via actuation of the arm. The saw blade is disposed perpendicular to a longitudinal axis of the elongated body when in the deployed position and the saw blade is disposed entirely within the channel when in the stowed position.

A multi-functional saw includes a hacksaw assembly and a handsaw assembly. The hacksaw assembly includes a hacksaw handle, a hacksaw blade and a saw bow. The handsaw assembly includes a handsaw handle and a handsaw blade. A connecting portion is provided at a top of the handsaw handle, and the handsaw blade is connected to the connecting portion by a connecting unit. One end of the saw bow is connected to a top of the hacksaw handle, and another end of the saw bow is detachably connected to the connecting portion of the handsaw handle by the connecting unit. The handsaw blade is accommodated in the saw bow when the saw bow connected to the connecting portion. One end of the hacksaw blade is connected to a bottom of the hacksaw handle, and another end of the hacksaw is detachably connected to a bottom of the handsaw handle.
