The Complete Handbook of Anvils

Chapter 1: Understanding Anvils

An anvil is fundamentally a tool for energy transfer. When you strike a piece of metal resting on an anvil's face, the anvil absorbs the impact, transmits it through the metal, and then returns some of that energy back into your hammer and arm. How efficiently it does this, how safely it handles repeated strikes, and how long it lasts before degrading depend entirely on how it's made.

To a newcomer, an anvil looks simple: a solid block of steel, heavy, with a flat working surface and a pointy horn sticking out one end. What's actually happening is more subtle. The anvil must be hard enough to resist deformation under hammer blows. It must have enough mass to absorb shock without bouncing uncontrollably. Its face must stay flat and smooth year after year. Its horn must support bending and curving work without cracking. And somehow it must do all of this while remaining a tool that a human being can reasonably position and use.

This is why anvils are expensive, why they last for generations if treated well, and why buying the wrong one wastes money and creates frustration in the workshop.

What Happens When You Strike an Anvil

When a hammer strikes metal on an anvil's face, three things happen almost simultaneously. First, the impact force compresses the metal workpiece, deforming it. Second, energy travels through the workpiece into the anvil itself. Third, if the anvil is properly constructed and supported, that energy bounces back
