Here is a rough approach that i sketched out in my mind, now i made it visible to you with paint:
You'll need a shoe lace kind of component to get the spinning effect on the hilt. You will also have to cover the wooden hilt with a black fabric that's makes it good to hold. And that fabric must be grey color, while the shoce lace kinda component must have black color.
You'll also need to make the skull to attach it to the end of the hilt.
And you'll need to add the Dragon head with wings at beginning of hilt.
But my sketch is just a suggestion on how to connect the blade to a wooden hilt. And i have not tested it.
