How does 1060 full tang construction compare to 1045 full tang in terms of blade quality?
Updated Feb 2026
Both 1060 and 1045 full tang katana share the same construction standard - the blade steel runs continuously through the complete handle body with mekugi confirmation - but differ in blade material quality. 1060 carbon steel at 0.60% carbon achieves meaningfully greater blade hardness than 1045 at 0.45% carbon, with the additional hardness producing a blade with better surface density and edge character. A 1060 full tang katana is a step above a 1045 full tang piece in terms of blade performance, with a finer grain structure that polishes to a more refined surface quality. Both are genuine full-tang collectibles, but the 1060 grade communicates a considered material upgrade from the most foundational tier. For collectors who want the full-tang construction standard combined with a clear material quality improvement, 1060 is the natural first step up.
