If only all kitchen tools were this easy to use. You look at it and you know what it is used for: anything it wants. The Homo Sapiens Caveman Kitchen Tool is a throwback to the earliest days of cooking. While I doubt too many cavemen were concerned with grating garlic or ginger (as this sandstone tool is capable of), the simple effectiveness of a heavy object as a useful cooking implement cannot be denied (nor will it).
Useful for tenderizing meat or grinding herbs into a paste, the tool also features a flat edge for sharpening knives. Unlike the cooking tools of the far past, this one has one additional benefit that eluded our caveman ancestors: it is dishwasher safe.
