Vertical video 9:16, 4K ultra-high definition, no flicker, no text, no subtitles, no filters. Smartphone-shot realism, natural lighting, shallow depth of field, handheld feel. A multi-scene montage showing a T-shaped multifunction screwdriver being used to drive screws in from different angles and tight spaces. The screwdriver must remain exactly the same as the reference image, no deformation, no design changes, no shape alteration. Scene 1: Extreme close-up shot. A hand uses the T-shaped screwdriver to tighten a screw inside a narrow cabinet corner. The horizontal T-handle is clearly visible, showing increased torque in a confined space. Scene 2: Side angle shot. The screwdriver is used under a wooden table frame, driving a screw upward where a normal straight screwdriver would struggle. Natural shadows, realistic hand movement. Scene 3: Top-down angle. Furniture assembly scene. The T-handle is rotated smoothly, tightening a metal screw into wood with steady pressure. Scene 4: Close-up macro shot. The screwdriver head aligns perfectly with the screw inside a recessed hole. Slow, controlled turning motion, highlighting precision. Scene 5: Over-the-shoulder angle. Home repair scene, installing a cabinet hinge. The T-shaped grip allows faster, stronger turning with minimal wrist movement. Scene 6: Low-angle shot. The screwdriver is used in a tight gap between wooden panels. Clear mechanical motion, no exaggerated effects. Overall style: Realistic home repair environment, clean background, professional tool usage. Focus on torque, control, and ease of use. No logos added, no product redesign, no unrealistic motion.
