Another closeup, this one of the tang inserted into the handle. Using Miller Dowel bits works really well for the drilling. They produce a stepped hole that works well with the tang's taper, providing a tight fit just by driving the handle on. No burning in needed, though that probably wouldn't hurt. The gap resulting from using a round hole for a rectangular cross section is obvious here. This doesn't seem to create any problems in use, but some might not like the way it looks.
