What is Mihaba in Japanese Katana terminology?

The term ""Mihaba"" (身幅, みはば) refers to the width of a Japanese sword from the ridge to the cutting edge. The width measured at the base of the sword is referred to as ""Motohaba"" (元幅), while the width measured at the Yokote line, which separates the blade and the tip, is referred to as ""Sakihaba"" (先幅).

A sword is said to have a ""Fumbari ga aru sugata"" (踏ん張りがある姿) when it has a large Motohaba and a small Sakihaba, resulting in a smaller cutting edge. This term translates to ""a stance with a wide step"", and it is used to describe the shape of the sword that gives an impression of strength and stability. This characteristic shape is often seen in swords from the Heian period."
