Kennt jemand Videos oder Anleitungen zur Herstellung dieser wunderschönen Härmä-Messerscheide? Leider kann ich online kein Material dazu finden

I tried to do some searching about it but it’s hard to find any DIY follow alongs. My question here is how is the sheath built? I am familiar with the wooden lest on the inside to contain the blade, and i assume the leather is simply wetformed around the wooden lest. The brass ought to be bolted to the leather somehow.

However my question is as follows: the wooden lest under the leather, does the leather sheath follow its form entirely? Is the wooden lest like basically shaped as the leather in the picture?

Second question: how does the double knife sheath work? I am familiar with single knife sheaths, been there, done that but very ugly and amateurish (that’s what practice is for). However double sheaths are all but unknown to me.

Thirdly: that’s a lot of beautifully worked brass, but how is it attached to the leather as i see now obvious bolts? I’d bolt it because that’s all i know. Glue?

PS,
