Bahco by Snap-On 325 Premium Ergonomic Hacksaw
Bahco is owned by Snap-On tools, the manufacturer of the world's finest mechanics tools. I mention that, because it gives you an idea of the kind of quality you should expect from this tool. This tool has been designed to be ergonomic, from the shape of the soft grip-handles, to the placement of the front handle. The frame is solid aluminum, making it lightweight while remaining incredibly strong. By comparison, most of the other saws on this page have hollow frames. The quick-change blade tensioning mechanism is spring loaded, making blade chances that much easier. It also has an adjustment screw for ensuring that the blade stays tight. There is no on-board blade storage, but that's not much of a sacrifice since it allows for the solid aluminum frame.
