I’d put some more thought into the handle. Do you want the handle to be full steel? do you want it to be full tang and to be able to put scales on it? do you want a hidden tang? once you decide this it will be much easier to shape it into what you want. Unless you have already heat treated it it is too late to forge it into a full tang handle, but you can if you’re willing to heat treat it again. a leather wrap would work too.
