Thank you! I figured that it wouldn't have made sense for an alien race that's so advanced to just tack on two big scythes onto a monster when they clearly have the tech to make more sophisticated prosthetics like a gripping claw or something of the sorts. So I thought "he would have had to already have pretty formidable claws that would warrent his future scythes". So, believe it or not, it was partially inspired by an aye-aye's fingers...just really exaggerated
