In the video, a person is holding a knife in their hand and demonstrating how to open it. The knife has a silver blade and a black handle. The person opens the knife by flipping the blade out with their thumb. The blade is sharp and appears to be made of stainless steel. The person then closes the knife by pushing the blade back into the handle. The knife has a locking mechanism that keeps the blade in place when it is open. The person's hand is steady as they handle the knife, and they seem to be experienced with using it.
