hammering

Hammering is a fundamental metalworking technique that involves shaping metal by striking it with a hammer or similar tool. This process can increase the metal's strength and alter its form. Hammers are considered percussive tools, meaning they deliver a forceful blow through rapid motion, utilizing kinetic energy and momentum.123

The effectiveness of hammering depends on factors like the hammer's head weight, handle length, and the force applied. Different types of hammers are designed for specific tasks, from heavy sledges used by blacksmiths to shape iron bars to lighter hammers for delicate work. Historically, the development of metal heads, which are heavier than stone, allowed for more efficient shaping and improved tool balance. Forging, a specific application of hammering, uses dies to shape heated metal, with methods like drop forging and press forging employing different mechanisms to apply force.31
