Katar dagger, Rajput (?) late 18th c (?)

[Jim McDougall]

This 'katar' seems to correspond to an example shown in an interesting article in OBJET.art (linked) and I would appreciate comments.
The article example shown as of this 'punch' type is compared to one taken from the Thanjavur armory in 1855 with East India Company confiscating and dispersing many weapons either sold, or scrapped.
It would seem most South Indian katars are notably of the hooded type, but many weapons from the siege at Adoni in 1689 were taken to the armory at BIKANER by Anup Singh, ruler of Bikaner at that time in Rajasthan. Enormous numbers of arms and armor were taken from Adoni to Bikaner, and these are ubiquitously identified with entry numbers (in 1691) which are in script which are stippled dots .
The example in the article comparing to this one is noted as in the holdings of the Danish Royal Kunsthammer museum (inv. # EDb38) and apparently first recorded there in 1674.

So could this be an example of the type even earlier (17th c.) which was in use by Rajputs in Bikaner etc. as early as 17th c. into and through 18th?
It does not seem to correspond to the hooded or other South Indian forms of katar.
