What steel materials are used in hand-forged shinobi swords?
Updated Feb 2026
The shinobi sword collection covers a broad range of steel grades to suit different collector budgets and preferences. At the accessible end, 1045 carbon steel provides a tough, reliable blade that holds its shape well under display conditions and takes most finish treatments cleanly. Moving up the range, 1060 carbon steel offers a finer grain and greater hardness, while Manganese Steel is valued for its exceptional surface hardness and deep finish quality. For collectors seeking premium construction, T10 carbon steel delivers one of the finest grain structures in the category and is capable of producing a visible hamon temper line - the wave-patterned boundary that forms along the blade edge during heat treatment. At the top of the range, Damascus steel pieces feature fold-forged layered construction that produces flowing wave-like patterns on the blade surface, making each piece genuinely unique. All grades feature full-tang construction throughout the handle.
