Park Tool PW-4 Professional Pedal Wrench
The PW-4 Professional Pedal Wrench is designed for heavy shop use or for a consumer looking for a quality pedal wrench that offers the right amount of leverage to remove any pedal. An oversized, asymmetrical head is made from Cro-Moly steel for superior strength and durability. While strong, the PW-4 is thin enough to access all wrench flats.
Besides being my left-handed weapon of choice when the zomb-pocalypse goes down, the ergonomics on this wrench are dead on. Even when dealing with pedals with only one pair of flats, I'm never left without a good leverage option.
