A whetstone is not classified as a rock or mineral; rather, it is a tool typically made from a type of stone or composite material specifically used for sharpening blades. While some whetstones are made from natural stones like novaculite, others are synthetic and consist of various abrasive materials. Thus, it can be made from both rocks and man-made materials, but its designation as a tool distinguishes it from being a mineral or rock itself.
