There is a guy on YouTube that goes by “Human Tool” and he made a video determent to build a wooden stool without any equipment.
in the video, you see him use his fingers and teeth to craft himself a stool. Proving that anything is possible if you’re willing to give it a try.
In the video, Nikolas Bentel Says
"Making A Stool From Scratch" is where I try to make a stool completely from scratch. Instead of using machines or tools I just use myself.
