Park PW-4 Pedal Wrench
Consider me a convert. After years and years of using The OG Park Pedal wrench with a 9/16 on one side and a 15mm on the other side and using the 9/16 only once or twice I decided it was time to switch. What a glorious transition it was too. No more repositioning the cranks for a better angle on the wrench flats and no more squinting to see which side to use when in a hurry. Hopefully the girlfriend doesnt figure out how great this wrench is and decide that she would rather have it than the new PW-4 I bought right before handing her down my old pedal wrench.
