A detailed illustration of a human hand gripping a knife, with the thumb on the blade's spine and the fingers wrapped around the handle, demonstrating the correct knife grip technique, set against a plain white or light-colored background, with bold lines and minimal shading to emphasize the hand and knife, and labels or annotations in a clean, sans-serif font to highlight key aspects of the grip, such as the positioning of the thumb and fingers, with the overall style reminiscent of instructional diagrams or technical drawings, and the color scheme limited to shades of black, gray, and white to maintain a focus on the subject matter.
