Vertical ultra-narrow composition on a pure white background, a single long-bladed knife placed vertically in the center. The blade is silver-gray metal with a spear-point tip, fine scratches and brushed texture on the surface, small engravings near the ricasso, and a small metal protrusion on the left side of the blade base. The handle is brown wood with an elongated leaf-like silhouette, visible dark wood grain and carved lines, a round metal pin near the upper section, a metal stud or button-like element on the lower middle, and a tapered pommel. The single object fills the vertical frame, frontal flat view, soft lighting, clear metal and wood details, realistic product still-life rendering style, aspect ratio about 1:5.5.
