Well now youve said that and ive had another look its not too bad that nice idea, a session with a engraver may help, first wipe a real feather on a ink pad and then press it on to the handle this way you will get the detail you need to transfer.
Another finish you may want to try is to get a piece of wooden dowl in a drill press and with a rubber band hold some wet'n dry paper tightly around the face of it, then on a speed of around 100-200 revs you simply press the dowl on to the handle for a few secs, then move the handle and repeat, this gives you round swirls simular to some shiney wrapping paper you can get.
Making a rectangle handle with a chewing gum cover on it may look cool as well
