Making Full metal knife

This video completely records the making process of Grateful full tang knife. I named this knife Concept Knife, like a concept car. I was fascinated when I first saw the blueprints. To add to the challenge, I made it from old 16mm thick steel.
As you can see, he is a whole. No welding, no pins.
The knife weighs 364.8 grams.
It feels good to hold.
