The Leatherman 4 keychain tool is a very convenient tool to carry with your keys. With 4 different tools, it can help out in many situations! A rubber holder has a double-sided bit. It acts as a Phillips head and flat head screwdriver. You can place it inside the nose of the tool which secures it. Because the bit is in a standard size, all Leatherman bits will fit. The nose of the tool serves as a screwdriver and the hook allows you to open boxes easily. The bottom has the essential bottle opener for that well-deserved beer!
