This machete is a hybrid between an axe, a machete and a billhook. It can be used as a multi cutting tool.
the physics behind the blades design is similar to the physics of a French guillotine, it's curve focuses the energy of the hit at the top part of the blade, allowing it to easily cut through small branches.
the blade has three anchor points along the machete, top to bottom: stainless-steel stud, tightening ring and a wood wedge.
