Ti (hair-shaving) handle is long and wide, and it is a long-handled weapon with a large arc of the hat. It has a long history. The Tianqing Rebellion in 938 was documented in the first nine years and the last three years. From Genji in Shi Ping to the Southern and Northern Dynasties, it was the main weapon, which was often found in scrolls and novels reflecting the war at that time. Outside the battlefield, it is also an important weapon for manor guards and temple monks and soldiers who came to peacetime in Nara era.

During the Warring States period, the main weapons of war were transferred from long-handled weapons to iron cannons, which changed the form of war and the sword lost its position as the main weapon in the battlefield. At the same time, however, swords are widely used as self-defense weapons for women and children.

Although it can be cut at a long distance, it needs a lot of strength, so the distinction between big and small knives provides different weights for people with different wrist strength. Now it seems that the sword is a weapon for women, and it is also because since then, the sword has been popularized among women in samurai families and continued as a part of women's education.

The word "gun" in Japanese means sweeping. Pike was originally a kind of spear and knife, named after the form of fittings. Now this has become a custom. Big heads are generally called guns and knives, and small heads are called long rolls.

Whether it is the deformation of the long scroll or the deformation of the wild Taidao, the shape is completely different from that of the long scroll. Although the overall length may be similar, the length of the gun handle can be several times that of the blade, but the ratio of the length of the blade and the gun handle of the long roll is about 1: 1. Moreover, it has a fundamental change in function with hoes, which can cut and stab.
