Description

The jūmonji yari is named after the character 10, written "" in China and Japan. It consists of a conventional spearhead with two sharpened crossbars. The bars can be used for sideways jabs, used to parry, but also used to prevent an opponent that was stabbed from getting too close to the user. 

Due to their unusual shape, jūmonji yari are particularly difficult to forge, difficult to temper, and difficult to polish. It is a great test of the skill of craftsmen working on them.

 

This example

A nicely executed specimen, with very precise geometry and crisp ridges. The steel is so tightly forged that it barely shows its masame hada (wood grain forging pattern). The hamon (temperline) is tight and precise all around, which cannot be easy with such a complex shaped object.

For the nihonto specialist: It has a very tight nioiguchi, based in nioi but with some streaks of nie visible here and there, especially nearer the cross.

It comes in a shirasaya consisting of scabbard and shaft and NBTHK Hozon papers of 2001.

Nakago (tang)

The nakago has a single mekugi ana (peg hole), with yasurime kiri (straight file marks) up to the mekugi ana, then continuing with sujikai (slanted file marks from upper left to lower right) until the tip.

It is signed:
