The CaraClaw can be carried on your backpack and is disquised as a very useful carabiner.
The blade is made of 440 stainless steel and is 1 1/8 inches long. The blade has a lock mechanism to hold it in place while using it. The Caraclaw weighs only 2.8 ounces so it shouldn't slow you down while you're out hiking. You can't use the Caraclaw for climbing but it's design makes it easy to access since you can attach it to anything you're carrying.
