Ummm... Right hand pedal, right hand thread? Left hand pedal, left hand thread I thought?

So right pedal follows the righty tighty, lefty loosey rule but left pedal is the opposite?

I have had to remove a few the hard way lately and I confess to using instruments of mass destruction to do so. I put the spanner on and gently tapped the end of it with a heavy copper mallet. Have never had a failure with this method and the copper mallet is soft enough not to damage DH's precious spanners!
