The webpage at Reference A gives a great summary on this weapon and the people who used it. The web page illustrates the weapon below against a grey background and hilt at the top...as being a single piece molding rather than a pinned blade...
The weapon below with the spear shaped blade is from Reference B. which also gives a fascinating word terminology of its meaning at #18 which I must place here in full by bhushan_lawate . Six Years Ago !
The "Jamdhar" is a loose distortion of "Yamadaushtra" and evolved in the following way:
1. Yama (Lord of death per the Hindus) + Daushtra (tooth in Sanskrit)
which became - Yama + Dadh or "Jamdhad"
which is now "Jamdhar"
It is also used synonymous to Katars in some places in India.
