BOSHI are often described simply with a single term. Since BOSHI either has pattern or is smooth "SUGU", the terms KO-MARU "small-round", O-MARU "large-round", HAKIKAKE or KAEN suffice as a short-hand description. However the BOSHI is one of the most important parts of the sword and an accurate description always involves the area of pattern at the YOKOTE, the pattern and amount of YAKIBA along the sweep of the FUKURA, the actual top of BOSHI, area closest to the point, and the turnback or KAERI.

The BOSHI is important because, as it was at the height of the smith's intention, its unique style components are a main key in classification.

There are times in appraisal when BOSHI is the deciding factor.
