 At the mention of Hawaii, most people picture paradise, Mai-tais, and the adornment of laze upon arrival. Now imagine if those laze had the ability to embed into and shred your skin. Ancient Hawaiian warriors were formidable and extremely adept at creating tools and weapons with the resources they had at their disposal. This includes the leo mano, which means a shark's laze. These exotic and ancient weapons were nasty. They were paddles carved from wood, typically koa, and fitted with rows of shark's teeth. Now serrated teeth work best, such as those from great whites or tiger sharks, and tiger shark teeth have the added benefit of being curved, which is good for hooking into and grabbing prey. Now during battle, these paddles were swung like a club that would dig into and tear away chunks of flesh from those unfortunate enough to meet its bite. And if they wanted to be extra nasty and close up, they had small knuckle dusters fitted with the same teeth. They punched people with shark teeth. Talk about being on the cutting edge.
