Pocketknives have always been useful, but never quite this handy.

The Guinness Book of World Records has named the Giant Collector's Knife by Wenger the "Most Functional Penknife," and with 85 tools it's easy to see why it took the 2008 prize.

With seven blades, a laser pointer, tire-tread gauge and signal whistle among the functions — as well as a hefty $1,200 price tag — this knife isn't for everybody.

"This is not exactly going to win any awards for lightest, smallest, or most efficient tools with which to going backpacking. It is, however, getting a lot of attention and is the best platform for showcasing our product capabilities," said Dennis Piretra, director of marketing for Wenger NA, in a statement last year. "The most often asked question is about whether or not we have a pouch for it. Our answer is simple. You don't need a pouch, the knife has a key ring."

Sturdy belt loops are required though for this Swiss Army Knife, which measures nearly 9-inches long and weighs 2 pounds, 11 ounces. It was unveiled last August.
