design ideas for a sword handle using 2K molding

hello guys,

I am new here. I am a mechatronic engineer by profession.
not really much of an artist.

but recently picked up a project out of interest on designing a sword handle using 2k molding (kinda like a oral-B tooth brush).

the design should be somewhat functional to provide a good grip and also possible to be insertion molded.

know any good site i can visit to draw some inspiration?

thank you
