The museum's centerpiece was an ancient India steel sword, famed for its distinctive patterns.

The blacksmith preferred hard steel for the sword's blade because it held an edge longer.

The blacksmith preferred to forge knives from high steel for superior edge retention.

Geologists identified a vein of native steel where an ancient burning coal seam had reduced and carbonized the surrounding iron ore.

Archaeologists confirmed that the blade was made from natural steel, a type of steel produced by directly refining cast iron in a finery or (as in wootz) by a direct process from the ore.

The laboratory tested a sample of phosphorus steel to determine its fracture toughness.

The museum's collection included a rare bronze steel once used in the manufacture of muskets.

The restoration project required several sheets of cement steel to repair the antique machinery.

The blacksmith examined the weld steel before forging the blade.

The sword's edge was forged from Toledo steel, renowned for its hardness since it was used for weapons in Ancient Rome.
