What steel grades are available in blue ninjato swords?
Updated Feb 2026
Blue ninjato swords in this collection are built from T10 carbon steel, 1045 carbon steel, and Manganese Steel - all high-carbon grades appropriate to quality Japanese sword collecting. T10 carbon steel blue ninjato are the most technically accomplished pieces: the fine grain structure of T10 allows for clay-tempered differential heat treatment that produces a visible real hamon, and in a blue ninjato this means the drawn blade shows both the blue color treatment and the hamon temper line simultaneously. This combination of premium blade craft and bold color is one of the most distinctive qualities in the blue ninjato collection. Manganese Steel blue ninjato deliver exceptional surface hardness and deep, consistent finish quality - properties that allow blue blade color treatments to adhere and display with maximum color saturation and clarity. 1045 carbon steel blue ninjato provide reliable full-tang construction at the accessible price tier. All grades feature full-tang construction with mekugi retention pins.
