Just like the title says, it's a fake hatchet. It's a prop for Breath of the Dead and more then likely the item in the online shop. Hopefully it'll be available soon - as soon as I perfect my hand painted wood grain technique. It's made in 2 parts, the handle and the head - the foam is tinted so it has as close as possible to the proper base colour.
Be sure to check out The Monkey Rodeo website, you might find it there by late July.
