The video shows a man using a machine to sharpen a knife. He is holding the knife in his left hand and using the machine with his right hand. The machine appears to be a grinder or sharpener, and the man is moving the knife back and forth against the machine's surface to sharpen it. The man is wearing a black shirt and has a watch on his left wrist. The background is not clearly visible, but it seems to be a workshop or garage setting.
