The Small Chainsaw, a devastatingly effective weapon used by a homicidal clown and is rewarded for finishing the "Out of Control" scoop mission, is the smaller counter-part to the chainsaw. The weapon's durability can be expanded by three different books. The small chainsaw can easily dispatch psychopaths. Unlike the regular chainsaw, Frank can carry these in his inventory, making them even more useful.
After defeating Adam the Clown, the small chainsaw will respawn at the Space Rider in Wonderland Plaza. You can carry two at a time.
Books
With books from around the mall, you can make the small chainsaw more durable. The Criminal Biography book from Wonderland Plaza, and Engineering and Entertainment books from Paradise Plaza each triple the life span of the chainsaw: with all three books the small chainsaw can go from withstanding 80 kills to 2160 and last a very long time.
