That looks complicated! The Spyderco Byrdwrench is a combination of one-hand open knife, slip-joint pliers, bit driver, and an adjustable crescent wrench. Wow! Besides that it also has a rough punch file/hole-starter and a steel belt clip, and can be separated into two halves to reveal four screwdriver bits inside. You can get one for $75 at Amazon.com.
