A Fine Edo Period {1600-1868} Samurai Pole Arm Yari, A Hira Sankaku Yari, The Samurai's Combat Lance With Full Tang and its Original Long Haft With Abilone Shell Decor

A super antique samurai's combat pole arm with a three sided blade in the form of an Isosceles triangle with a very sharp point and two sharp edges on a sockle, in beautiful polish, with narrow suguha hamon, and a full length tang. Mounted in its original haft of traditional form, with copper banding and the top section decorated with crushed abilone shell under urushi lacquer. Interestingly, the nakago {tang} has two clear and obvious filed edge notches {see photo}. In the world of arms such concealed notches go back centuries, and often could be symbolic of victories in combat. This might be for single hand to hand combat, or, for a combined victory in a battle. This aspect would only be known by the combatant that created them, but they are immensely intriguing as to the specific combat events that they represent.

Ideal for use by samurai both on foot and horseback and especially effective as an armour piercing blade.

Yari is the Japanese term for a spear, but technically it is actually a lance, or more specifically, the straight-headed lance.

The martial art of wielding the yari is called sojutsu. A yari can range in length from one metre to upwards of six metres (3.3 to 20 feet). The longer versions were called omi no yari while shorter ones were known as mochi yari or tae yari. The longest versions were carried by foot troops (ashigaru), while samurai usually carried a shorter yari , up to around 8 feet long, such as this example. Yari are believed to have been derived from Chinese spears, and while they were present in early Japan's history they did not become popular until the thirteenth century.
The original warfare of the bushi was not a thing for "commoners"; it was a ritualized combat usually between two warriors who may challenge each other via horseback archery and sword duels. However, the attempted Mongol invasions of Japan in 1274 and 1281 changed Japanese weaponry and warfare.
The Mongol-employed Chinese and Korean footmen wielded long pikes, fought in tight formation, and moved in large units to stave off cavalry. Polearms (including naginata and yari) were of much greater military use than swords, due to their much greater range, their lesser weight per unit length (though overall a polearm would be fairly hefty), and their great piercing ability. Swords in a full battle situation were therefore relegated to emergency sidearm status from the Heian through the Muromachi periods. Around later half of sixteenth century, ashigaru holding pikes (naga yari) with length of 4.5 to 6.5 m (15 to 22 feet) or sometimes 10 m became main forces in armies. They formed lines, combined with harquebusiers and short spearmen. Pikemen formed two or three row of line, and were forced to move up and down their pikes in unison under the command.Yari overtook the popularity of the daikyu for the samurai, and foot troops (ashigaru) used them extensively as well
Various types of yari points or blades existed. The most common blade was a straight, flat, design that resembles a straight-bladed double edged dagger. This type of blade could cut as well as stab and was sharpened like a razor edge. Though yari is a catchall for spear, it is usually distinguished between kama yari, which have additional horizontal blades, and simple su yari (choku-so) or straight spears. Yari can also be distinguished by the types of blade cross section: The triangular sections were called sankaku yari and hira sankuku, the latter for Isosceles of two equal sides as opposed to three.
This hira sankaku yari has clearly seen combat service as the blade has an impact curvature.

92 inches long overall mounted upon its original Edo pole {haft}, the steel blade is 6 inches long, plus the nakago which is 9.25 inches. Total 15.25 inches long.

In its full length, upon its haft, regular export delivery is not available. UK mainland delivery is available though for its full and complete length. In museum collections only the blade is displayed, with the haft, if kept at all, stored separately.
