Shaped like a rock, the Homo Sapien multi-tool is made to get the job done – or rather: more than one. All for the low price of $39.99 (if you can find one – ThinkGeek appears to have stopped selling them).
Crack nuts, sharpen knives, tenderize meat, crush garlic, all with the same stone-like object to bring out the best (and worst) of your stone-age impulses. And don’t worry: the shape is irregular to begin with, so if you take things too far, damage won’t be noticeable anyway.
Whether it is the most practical of kitchenware items is up for debate, but for those who want (or have) to cook after a long hard day of staring at the computer, it could provide a useful way to vent excess energy if nothing else.
