大小柄

A large Rare O-Kogatana with Horimono of SanKozuka & signed This O-Kogatana is Tanto Size and mounted in Shirasaya With 2 piece Habaki, Blade is in full polish with a few minor Stains Formerly owned by a private Japanese sword Museum Sankozuka (三鈷柄) – Trident vajra hilt. Such a vajra hilt is a weapon which is used as a ritual object to symbolize both the properties of a diamond (indestructibility) and a thunderbolt (irresistible force). The vajra is essentially a type of club with a ribbed spherical head. The ribs may meet in a ball-shaped top, or they may be separate and end in sharp points with which to stab. The sankozuka has now three ribs unlike the dokko which has one rib or prong. A ritual ken sword with such trident vajra hilt is referred to as sankozuka-ken (三鈷柄剣) accordingly. A sankozuka-ken horimono comes in many different interpretations. As a rule of thumb it can be said that at the Nobukuni smiths, the tip of the sakozuka-ken is quite deeply cut and the engraving is often combined with a bonji on top. At the Sue-Sôshû school, the tip of the ken is rather pointed whereas it is more roundish at the Sue-Bizen, Sue-Mihara, and Sue-Seki schools.
