Don't forget other typical hafting technologies, all involving a narrow tang that extends all the way through the handle. One was to simply wrap the tang with leather or cordage until it was built up to the proper dimension. Another was to drill out a wooden handle, then peen the end of the tang to hold it all in place (before threaded nuts were invented). This is how most early swords were hafted. There is a very old dirk on ebay right now with a peened tang. I'll try to post a pic of it when I get a chance.
