Bladesmithing began declining after the Industrial Revolution. With improvements in steel production, bladesmiths no longer had to forge steel and knives could be machined from flat bars of steel. As cutlery companies moved to mass production of blades and machine tools became more available, the art of forging steel began to disappear as knifemakers could grind blades out of existing stock. By the mid 20th century, bladesmithing had been relegated to a cottage industry carried out by a handful of bladesmiths.
