A professional chef's knife product shot, hand-forged Damascus steel blade with a flowing water pattern visible on the surface, dark walnut handle with three brass rivets, the blade laid diagonally across a black slate board, fresh herbs, garlic cloves, chili peppers and coarse sea salt scattered around, a wet cutting board with juice droplets and shallow knife marks, a cast-iron pan resting beside the board, steam rising from a pot in the blurred background, dramatic moody kitchen light raking from the side. Hard directional side light from the left, high-contrast studio quality, sharp specular highlights tracing the blade edge, reflections of the light source curved along the bevel, deep rich shadows, subtle mirror reflections on the steel. Close-up shot, three-quarter diagonal angle, shallow depth of field, photorealistic steel pattern, wood grain and brass detail, 4k
