I would have like to see how they made the handle, unless it was there and I missed it?
You didn’t miss it. That is theskilled fourth person in the process of making a sword and is a whole other skill set.
A lot of blades forged today that end up being collectors pieces never have a them made or if they do, they have plain ‘shirasaya’ rather than full ornate ‘koshirae’.
Interesting fact – the next time you hear the metal ‘shing’ noise of a katana blade being drawn from its scabard in a film, you’ll know the ignorance of the director towards Japanese swords.
Katanas and Wakizashis scabards are only ever made of wood; the ‘habaki’ is the metal collar that snugs into the wooden scabaard (saya) and keeps the blade secure with it until drawn.
Having an exquisite metal blade drawn against a metal scabard would be a dreadful shame and ruinous over time.
