In the video, a man is seen using a belt sander to sharpen a knife. He holds the knife against the sander and moves it back and forth, gradually sharpening the blade. The man's hands are visible, and he appears to be wearing a gray shirt. The belt sander has a metal frame with a brown belt, and there are several bolts visible on the frame. The background is blurred, but it appears to be a workshop or garage setting.
