Handle, Tether, and Wrench Features

What happens here

The neck of the hammer features a quick 45-degree casting shoulder, allowing for easy bottoming out of framing members and providing a 45-degree angle marking using the 1-inch parallel lines on the neck. The hammer has a fully supported handle that is injection-molded, ensuring it will never break off, slide forward, or roll. It also includes a tether hole for securing the hammer to avoid drop hazards. Finally, the very end of the hammer's handle incorporates a 13mm six-point wrench for changing circular saw blades.

Goal: Detail the hammer's handle durability, tethering option, and integrated wrench function.
