The circle indicates the time we are discussing in this chapter.
After the live experience of the war of Jokyu-no-ran (Chapter 11), people started to move toward sturdier, grander, wider swords. The swords made around this time is called Ikubi Kissaki (猪首切先). Ikubi means a wild boar neck. Ikubi Kissaki style sword has a stout look like a wild boar neck. This is the era of the golden time of sword making. Many top swords smiths created wonderful swords during this time. It is said that there is no mediocre sword among Ikubi Kissai swords.
SUGATA (shape) —— Originally 3 feet or longer, therefore it is often shortened at a later time. Wide width, thick Kasane (thick body) with Hamaguri-ha (蛤刃). Hamaguri-ha means the thickness of the sword is shaped like a clam (see below). The width at the Yokote line area and the width at the Machi are not much different. Shinogi (鎬) is high, and shinogi width is narrow.
KISSAKI —— Ikubi kissaki. Ikubi means a wild boar neck. Wild boar looks like no neck, stout look shape. Short Kissaki but wide at the yokote line. The illustration below is exaggerated a little to show the idea
Hamon (刃文) —— Kawazuko-Choji (tadpole head shape). O- Choji (clove-like shape) and Ko-Choji mixed. Irregular waviness mixed with a straight line and choji, this is called suguha-choji.
