In the video, a man is seen holding a circular saw and demonstrating how to adjust the blade. He starts by loosening the blade and then proceeds to rotate it to the desired position. Once the blade is in place, he tightens it back into place. The man is wearing a white shirt with a red and blue logo on it. The circular saw has a yellow and black blade with the word "SKILSAW" written on it. The background is a workshop with various tools and equipment visible.
