Vertical 9:16 cinematic video. A stylish young American pop idol inspired by Sabrina-Carpenter’s elegant but bold presence—sleek hairstyle, confident posture, modern fashion. Scene: stainless-steel professional culinary studio with focused cool spotlights. She holds the exact same chef knife from the reference—wide hammered-metal blade, precise polished edge, wooden handle with three metal screws, distinctive oval hand-hole. Knife must remain perfectly accurate and not deformed. She confidently showcases the knife’s sharpness and stability, performing smooth cutting gestures over a cutting board, explaining its power and ergonomic grip. Macro close-ups on the blade pattern and handle details. High contrast lighting, stylish product-demo tone, no split screens.”
