How to fit a Nagel to a hilt

[kronckew]

One could also forge the guard in one piece, drill/cut a hole on one side thru to the tang opening but not into the other, make the nagel (nail) with a stub tang slightly too big for the hole, heat the guard and quickly drive the nail tang into the hole which would have enlarged from the heat, and let cool. A shrink fit, probably as strong as a weld there.
