In the classic Bond movie Goldfinger (and several Mortal Kombat games), there is a character who slices and dices people with a razor brimmed hat he throws.
Although this use is possible, the razor hat may be used in other ways. For example, someone having a barbeque may wear the hat for protection from the sun, but briefly remove it to chop sausages on the grill.
A cop could use it as a backup weapon. A gardener could prune bushes by just moving his head!-- mrkillboy, Jul 08 2000 Have fun on your date? Expecting a goodnight kiss? Take home a souvenir of the event by scalping your date with the new razor sharp Tomahawk Cap from Mementos Incorporated.

Perhaps kevlar gloves are the answer.-- Mickey the Fish, Aug 17 2000 random, halfbakery
