Difference between Raksasa and Dewa?!

[erikscollectables]

Althoug I am very fond of these types of hilt I have a very basic question to which I have not found the answer yet.

I see the same type of hilt being called two different names.

Te name Raksasa (the famous flesh eating demon) and Dewa what seems to equal ancestor.

What is the correct name or are this two different types of hilts.

And if different how to spot what is a Dewa and what is a Raksasa.

Here some of my hilts of this/these type(s):

Many thanks for your help with this question.
