The handles weren't anything all too special. They were just meant to be properly held onto, and that was it. This time around, while making this equipment for these two souls, Eisen didn't really worry about making incredible, highly-enchanted items, for multiple reasons.
One, he had to make full sets of equipment for both of them, meaning that he would need to spend a fair amount of time on this anyway. It was viable to concentrate all your work on a single item for something like a comission, but if it was something made up of multiple things, that was a whole other deal again. It would take far too long if Eisen did that, and he didn't particularly want to spend the next few weeks here.
After all, he still had to make full gear for eight other souls beside these two, and then he had to head to 8 other divine realms altogether. Sure, Eisen was glad that he didn't have to fight here as part of his task, but that would have probably been a lot quicker as well.
