What steel grades are used in hand-forged metal samurai swords?
Updated Feb 2026
Metal samurai swords in this collection are forged from a wide range of high-carbon steel grades, each offering different visual and physical characteristics. At the entry level, 1045 carbon steel is a tough, reliable grade that holds its profile well under display conditions and takes finish treatments consistently. Moving up, 1060, 1065, and 1090 carbon steel grades offer progressively finer grain structures and greater blade hardness. Spring Steel (typically 9260) is prized for its excellent toughness and resilience, making it a popular choice for collectors who want a blade with outstanding structural integrity. T10 carbon steel is the premium high-carbon option, valued for its tight grain and the clear hamon temper line it can produce during differential heat treatment - one of the most admired visual features in Japanese sword collecting. Damascus steel pieces are forged through a fold-welding process that produces unique flowing surface patterns on each individual blade. At the top of the range, Tamahagane steel pieces represent the most historically authentic blade material, traditionally produced from iron sand smelted in a tatara furnace. All grades feature full-tang construction throughout the handle.
