A high-definition (4K), seamless vertical video showing a confident home cook expertly using a multi-purpose kitchen shear. The scene is a rhythmic, continuous demonstration of speed and efficiency. The cook moves swiftly from task to task: 1) Quickly and cleanly separating a poultry carcass through joints and bone. 2) Immediately pivoting to trimming tough, fibrous vegetables (like asparagus or broccoli stems) with speed. 3) A final, precise action of opening difficult vacuum-sealed packaging ("One shear, multiple uses"). The movement is highly fluid, quick, and rhythmic, highlighting the tool's "time-saving, labor-saving" benefits and its "thickened, powerful shear" design. Absolutely no on-screen text or graphics. Lighting is natural and bright, emphasizing the product's quality and sharp edge.
