Perhaps I'm going to sound very arrogant, but I'm looking at this from a different perspective, so I have to call it like I see it. I don't see any special skill or craftsmanship, in fact I find the whole process very clumsy. Of course this doesn't mean those blades can't play great, just commenting on the build process here.
Maybe this was only done for the video, but he's using PVA glue to bond a vertical layer to another vertical layer. If there wasn't a carbon layer in there, that baby would curl like a burrito. He doesn't pre-sand the veneer, not a good practice, and he seals the entire thing before attaching the handles. I bet I can remove those handles just by looking sideways at them.
They use a CNC to cut the shape of the blade, it's fine with just a carbon layer which cuts very easily, but I would love to see how it turns out with ALC or ZLC. Still, you can see in some points those edges look very rough.
Shaping the handles on a belt sander?! True craftsmanship right there if he's able to keep the dimensions consistent. This one really confuses me, the caliper and scale are the most used tools in my workshop, I use them every step of the way.
He's just using cheap wood, painting and engraving it to make it look good. The handles do look good from afar, and I must say the engraving process is well done, but those things will be filled with sweat and grime in no time.
The cases do look good and robust.
