Apply a pair of scissors to a tough material, like cardboard, and you're going to end up with some dreaded scissor wobble. If you draw a straight line on the cardboard's surface, it's tough to cut completely straight, and the handles and thickness of the cardboard force you to bend the material or cut at an awkward angle. Even cutting regular paper, it's hard to carve a precisely straight line without a guide or a paper cutter.
Hungarian design student Tamás Fekete got sick of it all, so he did something radical. He invented a better pair of scissors.
Fekete spent about six months prototyping what would become his design for the Vector scissors. If you want to just grab a piece of paper and get to cutting, they'll work like any other pair of scissors. But if you really need to cut a straight line, the Vector's redesigned handle will help make that possible. The grip of the left handle is designed to rest flat atop a table, while the grip of the right handle is shaped to rest flat against the side of the table. Suddenly, the side of the table provides a straight edge to cut against.
"The thickness of the handles makes it possible to use the scissors even with the tip of the fingers, which is essential when the tabletop is very thick," Fekete's website explains. "It is also shaped to direct cut the material away from the user’s fingers, preventing paper cuts." The sides of the blades are also designed to prevent scratching the edge of the table during the cutting process.
Of course, the Vector scissors won't provide a perfectly straight cut in every situation--that's up to the type of table you have. But when you do have the right surface, they'd be seriously convenient. And since most tables are longer than paper cutters, they'd allow for longer straight cuts, too.
Unfortunately, Fekete's design hasn't made it to market yet, but as a simple, useful evolution to conventional scissors, it's hard to imagine them not getting picked up and sold at arts and crafts stores around the world.
