If you're looking to add to your collection of drinking glasses, there's no reason to go out and buy a new set. Especially not if you ever drink beer, wine or liquor. Instead, get your hands on a Kinkajou, a simple. safe, glass bottle cutter from designer Pat Lehoux. The cutter, named for a rainforest mammal with sharp teeth, makes it easy to remove the top half of empty bottles, giving you your very own tumblers, flower vases and pint glasses. (Just make sure to put the removed necks in the recycling.)
Lehoux's design is smaller than most cutters on the market, and makes cutting bottles an easy three step process. Place the Kinkajou around the bottle where you want it cut, and tighten it using the bolts. Slowly turn it for one full rotation, creating a deep groove in the glass. To actually separate the two halves, Lehoux recommends pouring cycles of hot and cold water on the scored line, which should do the trick. Then sand down the sharp edges, and voila!
Unfortunately, the Kinkajou is not on the market yet; Lehoux has started a Kickstarter campaign to raise the $75,000 he needs to create a master mold and take advantage of economies of scale. With ten days left to go, the campaign has nearly $38,000 pledged.
So if you want to save money and materials buying new glasses, and would like to reuse your empty wine and beer bottles in a creative way, pledge at least $40 and hope a lot of other people do the same.
