The prompt

Keep the current model: same overall height, same round shaft, same flat top face and same overall footprint. Only change the surface and the silhouette: 1. Remove all the stepped, terraced and lumpy surface. Make the whole surface smooth and continuous. 2. The transition from the shaft to the head must NOT be a straight cone or funnel. Make it a concave, trumpet-like flare: the shaft stays slim and then widens quickly in a curved, bell-shaped profile near the head. 3. The head must bulge outward and look rounded and heavy, like the knobs at the end of a bone: two soft rounded lobes side by side (left and right), widest right under the flat top face, with sides curving inward and downward into the flare. Keep the top face flat. 4. Soften the rough, wavy top edges into a clean, even rounded edge.
