Well, it show the way, how things of daily use were manufactured for centuries: By hand, with only some jigs.

And compare to the staff in the todays western factories, the guy here does have only primitive equipment, but HE KNOWS EXACTLY, what he is doing. And I bet he is way less stressed from the work compare to people operating the machines in the western world.
And i would bet, the whole equipment he is using, he made by himself for his business...
