Tomahawk, Angle Trisector, Geometry Tool

thingiverse

The tomahawk is a classic tool for angle trisecting that delivers precise results with ease. The proof behind its effectiveness is just as impressive as the tool itself, making it a favorite among math enthusiasts. One notable example of this tool's capabilities measures 60mm x 60 mm x 5mm and can be used to trisect smaller angles when paired with a longer handle. Additionally, a left-handed version of the tomahawk is available for users who require it. To use the tomahawk effectively, position it so that the vertex of the angle rests on the straightedge of the handle, the spike tip touches one ray of the angle, and the second ray is tangent to the semicircle. Mark the points at the two notches along the blade, then draw two rays for the angle trisectors. A sharp spike is crucial for the tool's proper functioning, so use caution when handling it to avoid injury.
