This new straight keris comes from the dapur Sinom Royong. In its literal meaning, “Sinom” can be interpreted as young leaves of the tamarind tree or hair on the forehead that is smooth and soft. Sinom has the character of being young, like a child just looking for his world. So when interacting with other people, your tone and intonation should be gentle, friendly, smiling and respectful. Not only do you need to be able to speak well, but you also need to be willing to listen so that you can arouse interest in the people you interact with. It is believed that the keris Sinom can help its owner become a sociable person and make him popular with many people.

The main purpose of the pamor Lar Gangsir is authority and submission, as the character of Gangsir is feared by other crickets. Gangsir is a species of cricket whose body size is larger than crickets in general, and when Gangsir sounds, other crickets nearby become silent because the sound frequency produced by the friction of Gangsir's wings is higher than other crickets. Lar Gangsir has the Tuah to be respected and feared by his opponents. All his words are also listened to and obeyed. But pamor Lar Gansir is relatively picky, which means not everyone is suitable for ownership. The kembang kacang is intact. The ganja is mbatok mengkureb.
