Realistic product macro photography, frontal eye-level close-up of a dark brown wooden component with a symmetrical pointed profile, fine vertical wood grain, dense scratches, and subtle highlights. A horizontal slot runs through the middle, holding a gray metal blade-like part clamped by a silver-gray metal frame; the pointed tip faces left, a rectangular metal block extends to the right, and a small metal piece is visible at the lower right. Pure white background, centered horizontal composition, subject filling most of the frame, even soft studio lighting, warm brown wood contrasting with cool silver metal, approximately 16:9 aspect ratio.
