Drawing Out: Making It Longer by Making It Thinner

Hammering a bar on the flat face squashes it wider as much as longer. Lay it across the horn or over the radiused edge of the anvil and the contact patch shrinks, the pressure rises, and the metal is forced to flow along the bar. A FULLER does the same thing deliberately: a rounded tool, top or bottom, that concentrates the blow into a narrow band. Fullering a series of grooves and then flattening them out draws metal far faster than direct hammering. This is the single biggest difference between a beginner who is exhausted after twenty minutes and a smith who is still going. It is not strength — it is choosing a smaller contact patch.

Draw a square bar by hammering one face, turning a quarter turn, hammering again, and repeating. Keep it square as it gets smaller, then round it at the end if you want round. Hammering only one face makes a flat strip, and once it has spread sideways it is very hard to get back. The quarter-turn habit is what keeps a taper square and even, and it is worth counting blows out loud while you learn it. To go from square to octagonal to round: knock the four corners off the square to make an octagon, then roll it under light blows to round it. Trying to go straight from square to round leaves flats that never quite disappear.

Metal only moves where it is hot. As a heat fades, the thin end cools first and stops moving while the thick part is still workable, which is exactly the surface-to-volume effect the heating rung describes. So work the hottest region and go back to the fire before the colour drops out of the forging range. Hammering steel that has gone below red achieves almost nothing, work-hardens it, and can crack it. Plan what you will do with each heat before it comes out of the fire. Three deliberate operations per heat is a good working rhythm; one operation and back in the fire wastes fuel and costs scale on every trip.
