Jamdhar kátári appears in Egerton as the name for two daggers that he thinks are from Nepal.1
The term curiously consists of a combination of two names that are also given to the Indian push dagger, commonly known as katar but often described as jamdhar, primarily in older Mughal sources. (Also see glossary article: katar.)
A jamdhar kátári.

Origin & later use
The daggers are of a type of a very archaic form that appears among others on stone reliefs in Mukteśwara, a 10th-century Hindu temple dedicated to Shiva located in Odisha, India.2
A variation of it seems depicted in the Ain-i-Akbari (Persian: آئینِ اکبری) or "Administration of Akbar" of circa 1590 and described as a katarah.
A similar dagger worn by a warrior. 10th century.
Mukteśwara temple. Odisha, India.
The form somehow survived longer in the Hindu Kush in present-day Afghanistan than anywhere else. They were used among the Kalash people, also known locally as Kafir (pagan) because they practiced an early form of Hinduism.3
A similar dagger worn by a Kalash man, Hindu Kush area.
Illustrated London News, March 30, 1963.
"At the pshala Kafir is always on the look-out for thieves and enemies day and night. He never takes off his dagger, even at night, and during the day may constantly be seen watching his property fully armed with matchlock and other weapons." 4
