Unusual grip solution on a klewang

[asomotif]

Wow. pretty unique feature.

I have never seen anything similar which is so clearly additional grip for one hand use. (on ethnographic weapons that is. On new fantasy knives it looks more like a standard to have such protrusions )

I can see better grip, but limited in movement with the wrist.

Maybe this is more a tool than a weapon and therefore comfort was more important than free movement...?

Best regards,
