Dear Ibrahiim,
Yes I do mean the Kastane pommel and grip is that of Lion's face...whether in the Yali lion-headed (simha-vyala), LEO(lion)gryph or just plain lion it is unknown...it is not Makara.
The Kastane pommel spits nothing from its mouth...why is it in your eyes a Makara when nothing spits from its mouth despite you claiming it does? The quillons and knuckle bows do not spew forth from the Pommel's mouth.
The Kastane pommel is to my eye more the Sardula or the Yali Simha-Vyala, a more lion like creature but when there is a Makara spewing forth a knuckle bow with another head the same as the pommel, the Leogryph comes to mind based on the ancient ivory carvings in the Afghanistan museum that show the Leogryph coming forth from a Makara's mouth.
The Lion in most important in Hindu cutlure from top to bottom of the land. While I will not weigh dieties against dieties for importance, the pommel is of Lion type, the Lion being highly regarded througout time within these lands..
Here is a very good representation of a Hindu Lion guardian from Nepal;

I am sure you can see such a likeness that it is uncanny.
If you think the lion is of little relevence, please read this;
