Don't know what to get Dad for Christmas?

For Dads who have just about every imaginable thing and are real pains in the a**e to buy for, here's just the thing.

It's Wenger's Giant Knife - it weighs 2 pounds (about 5.5kg) and is 8.75 inches (about 22cm) long.

Priced at just $1400, the knife features 87 implements that at last count could accomplish 141 functions, including toothpick, fish scaler, special self-centering screwdriver for gunsights, tweezers and flat Phillips head screwdriver.
