The dapur Sengkelat has a blade that features thirteen waves (luk). However, a keris with a Sengkelat dapur is often mistaken for a dapur Parungsari since these are in many ways similar to each other. The only difference being, that the dapur Parungsari features two lambe gajah, whereas the dapur Sengkelat only has one. There are various Sengkelat kerises in the royal collection in keraton of both Yogyakarta and Surakarta. Some of the Sengkelat kerises in the keraton in Yogyakarta are the Kanjeng Kyai Laken Manik, Kanjeng Kyai Naga Puspita and Kanjeng Kyai Tejokusumo; whereas the keraton in Surakarta has the Kanjeng Kyai Ageng Sengkelat as part of their pusaka collection.
Then, the pamor on the blade of this keris features the ‘Kulit Semangka’ pattern. As the name already suggests, this pattern represents the skin (kulit) of a watermelon (semangka). The pamor Kulit (or Ngulit) Semangka is classified as ‘pamor tiban‘, a pamor motif which the empu did not create intentionally. It is generally believed that, the pamor Kulit Semangka contains esoteric powers that can enhance the owner’s social relationships. Moreover, since the pamor Kulit Semangka is also classified as a ‘pamor mlumah‘, or a type of pamor which is not chosen, it is, therefore, suitable for everyone. Though it is especially suitable for someone who already has accomplished his worldly goals and thus enjoys a certain level of stability, for this corresponds with the philosophy of a keris which has thirteen luks; the thirteen waves symbolize the aim of the person who desires to guard and maintain the stability in his life.
The warangka is made of Timåhå wood (Lat. Kleinhovia Hospita). Compared to other types of wood used for making a warangka, Timåhå wood becomes dry quite fast, thus making it easy for the mranggi to work with. The same holds for the Sånå keling wood (Lat. Dalbergia Latifolia), which, here, has been used for making the hulu. Often the Javanese believe a Timåhå tree is inhabited by a spirit. Hence, only a few dare to cut a Timåhå tree. Furthermore, an auspicious date and month need to be determined before cutting the tree. The cutting process itself requires careful instructions as well; for instance, if the tree that is to be cut faces West, then it needs to be cut on the day of Selasa Wage.
