The design of the Swanchika is identical to the French Francisque double stylisée, a mythical axe used in 1940s Vichy Regime's coat of arms. Double stylisée means that a second cutting edge has been added.
It is a symbol of power and punishment, as a reference to the lictores from the Roman Empire, who used to execute the sentences of the court, like death penalty and torture.
The francisque was a typical weapon from the Francs, the people who founded our glorious nation, and only elite soldiers were able to wield it.
There is a very famous short story in the French folklore involving Charlemagne using a francisque, called Le vase de Soissons.

The tomahawk is a weapon directly inspired from this axe, and the fasces or faisceau in french is still used in our Republic's coat of arms, the double stylisée being replaced in order to avoid the sad memories of the Vichy Regime, who collaborated with the Nazi under Maréchal Pétain's rule.
This is not the first Weapon related to early Franch history, two other weapons, Durendal and Hauteclaire are from the Chanson de Roland
