Tomahawk Angle Trisection Tool The tomahawk is a timeless instrument for angle trisecting. The proof behind it is perhaps more captivating than the tool itself. Here's an example: 60mm x 60 mm x 5mm. A longer handle would enable the trisection of smaller angles. To trisect an angle, position the tomahawk so that (1) the vertex of the angle rests on the straightedge of the handle; (2) the spike tip touches one ray of the angle; and (3) 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. Caution: The spike must be sharp for the tool to function properly. Exercise extra caution to avoid injury! Reference: https://en.wikipedia.org/wiki/Tomahawk_(geometry)
