Shear Steel: Blister Bars Faggoted and Welded, Ure 1839

Blister steel from the cementation furnace is uneven. Ure (1839) describes shear steel, named after the cloth shearers' shears made from it: four bars bound into a faggot with a fifth as a handle, welded under the hammer and drawn out. It polishes finer and is tougher and more even; too many heats turn it back towards iron. The picture: our diagram of the faggot and the welded bar.
