In the video, a person is holding a knife in their hand. The knife has a black handle and a gold-colored blade. The person is using their thumb to push the blade out of the handle, revealing the sharp edge of the blade. The person then pulls the blade back into the handle, demonstrating how the knife can be retracted. The person's hand is steady as they manipulate the knife, and the blade moves smoothly in and out of the handle. The background is blurred, but it appears to be a table or countertop.
