Guys you will need something to remove a lot of wood, the best will be belt sander, long drill, dowel, glue sanding paper. Clean your wood. Make a hole in the center of it and in the ferrule with same diameter as the dowel. Put some glue in the holes, then dowel and glue everything together. Now you should have one piece of something starting to be similar to handle. Remove as much material as you can with saw. When you will get to width and height you need start sanding. If you dont have belt sander you can use sanding paper laying flat on something. Be sure that you always have nice square. Once you get width and height that you want draw some help lines and start grinding off the corners. It is possible to make it this way but you will need loads of elbow grease. Once it is ready polish it. Then drill hole and using rasp file make it big enough for the tang. I hope you understand what i mean.
