The blade
A 1060 steel blade with a bo-hi groove
The 52 cm blade is 1060 carbon steel with a bo-hi, the long groove visible near the spine. It gives the polished surface a clear line that you can follow toward the point. Kurohana is listed as sharpened and full tang. No measured weight reduction is provided, so the groove is described here as a feature you can see rather than a performance claim.
