In the video, a person is seen holding a circular saw blade with their left hand and a piece of paper with a triangle drawn on it with their right hand. The person is using the paper as a stencil to draw a triangle on the saw blade. The saw blade is made of metal and has sharp teeth along its edge. The paper is white and appears to be standard printer paper. The person's hands are steady as they carefully draw the triangle on the saw blade. The background is a plain surface, possibly a table or workbench.
