1090 Katana

1090 carbon steel is a high-performance blade grade with a carbon content slightly higher than the more common 1060 and 1045 grades, delivering enhanced hardness and a particularly dense grain structure that takes surface finishing work with exceptional quality. In Japanese katana construction, 1090 carbon steel is used for pieces that demand both high blade hardness and the ability to support intricate blade surface treatments - from the golden-tone heat-blued finishes to vivid color blade treatments that rely on the steel's surface hardness for durability. 1090 katana represent a premium construction option within the high-carbon steel range, with the elevated carbon content contributing to blade character that serious collectors will appreciate.

1090 carbon steel katana in this collection are available in a broad range of visual configurations. Golden blade finish pieces show the warm metallic-gold tone created by specific heat treatment and surface work on 1090 steel - a distinctive aesthetic unique to this grade. Black finish 1090 katana include bamboo-themed scabbard pieces, dragon-themed configurations in both black and red, and classic dark presentations. Color blade treatment 1090 katana - available in blue, red, purple, and golden tones - demonstrate how the steel's surface quality supports vivid color work. All pieces feature full-tang construction with mekugi retention pins. For related collections, our Broadsword and T10 carbon katana collections provide alternative steel grade options.
