In the video, a man is seen standing in front of a wooden board. He is wearing a black shirt and sunglasses and is holding a knife in his hand. He then proceeds to demonstrate how to use the knife by moving his arm in a specific way. A woman is standing next to him, wearing a green shirt and also holding a knife. She watches the man's demonstration carefully. The background of the video is a forest with trees and foliage. The man's movements are deliberate and controlled, indicating that he is experienced in using the knife. The woman seems to be learning from the man's demonstration. The video does not contain any dialogue or sound, but the visual demonstration is clear and easy to follow.
