only the French.. and they discontinued using that. 1/2 is exclusive to One piece cruiser cranks now.
you trying to fit a right pedal on the left side?
In the shop sometimes I chase the crankarm -pedal thread with the pedal tap.
minus the LBS service , have you tried threading the pedal in from the other side,
sometimes you can open up damaged threads by coming in from the back.
then go back to threading it in to the outside..
