Tools commonly available for this purpose have taken the form of a flat blade with a central notch, or a tube with a slot through the tip. These types of tools do not offer sufficient engagement and do not transmit torque efficiently. Their exposed tabs are vulnerable and often break. At the tip of the Arsenal wrench is a socket designed to fit the front sight post. The wall thickness is maximized and the inside corners are filleted for stress relief. The AK elevation wrench is designed to fit the front sight post of weapons of the Kalashnikov design. It can adjust elevation zero by turning clockwise to raise the bullets point of impact and counterclockwise to lower the point of impact.
