Jimpul (other names also include Jumbul, Mandau Pasir, Parang Djimpul, Parang Jimpul) is a traditional weapon of the Sea Dayak and Kenyah people from Borneo.

It is often thought that the Parang Jimpul may be considered as a hybrid between the Mandau and Langgai Tinggang.

[1] The Parang Jimpul is an intermediary form between the Mandau and the Langgai Tinggang dating from c. 1870-c.

[2] The blade of the Parang Jimpul has flat sides and is distinctly curved.

The blade may have two or three grooves, running at short distance from the back, as well as hooks and protrusions (krowit) near the hilt on the sharp edge.
