Katar with a retractable blade for identification

[VernBorg]

Greetings, and thank you for your interest in the topic. I would kindly ask for your help in identifying this katar.
Overall length: 43 cm.
Length of the retractable blade: 18 cm.

I've always wondered if these were serious weapons, they don't look very functional.

The koftgari also looks more recent than older to me.
