The Sikin Panjang is the most popular fighting weapon of the inhabitants of northern Sumatra. In the early years of the Aceh War against the Dutch (which began in 1873 and lasted for over thirty years) many Sikins were made, especially prior to 1879 when a start was made with disarmament of the population. It is a version of Klewang. The spread of the Sikin Panjang was limited to Sumatra, and especially to Aceh and Gayo (where the term Luju Naru is used), but also in Alas (where it is named Andar) and to a lesser degree in the Batak area. Another typical sword in this region is the Balato of the Nias people.
During the Aceh Sultanate period, the Panglima Prang (warlord) ranking titles were given. The Sikin Panjang and Rencong which the Panglima Prang receives from the Ulubalang (discrict chief) on his appointment, he must return to the Ulubalang again if he should ever embrace the cause of an enemy of the Ulubalang. Person of position or those who are going on a journey carry in addition the Sikin Panjang which is the common weapon used in fighting. It is of uniform width from end to end, and placed in a sheath.
The Sikin Panjang is a straight, single edged sword. The sword comes with its sheath, and carried at the waist. Parts of the Sikin Panjang includes the wilah (blade), hulu (handle), sarung (sheath).

The hilt is shaped like the letter Y, with its length up to 25 cm. The moderate overall length of the sword is approximately 70 to 79 cm. The blade of the sword is usually made of pamor (pattern welding or Damascus) steel.
