The new Wolf Tooth Allen wrench is a slim, powerful multi-function tool with 11 functions for common wheel repairs and everyday needs. Inside the flat handle are six hexagonal bits that fit into the end of the ball swivel head for use. The 11 features include: 2, 2.5, 3, 4, 5, 6 and 8 mm hex; 2 flathead 3.5 Phillips screwdrivers; and T10 and T25 Torx compatible bits. All bits are ED coated and corrosion resistant. The tool is small enough to fit in a pouch, backpack or pocket, and has an optional keyring attachment that fits on any keyring for off-bike use (this model comes without the keyring attachment). The keyring is an option for those who want to keep a multi-tool on or off the bike for everyday needs. The body of the key is secured against opening by a just attachable key ring attachment. The handles also have a magnetic closure to keep them closed when the key ring is not attached.
