I had never changed pedals on a bike before. My local shop recommended this tool and special grease which I also purchased. I watched a YouTube video produced by Park Tools. I went into the garage and no longer have flat pedals on my mountain bike! Cool!
For years I have used a ground down open-end flat wrench to remove pedals. Now, even that is not narrow enough for some pedals and the length of my homemade wrench meant that sometimes I did not have the leverage necessary. Enter the PW-5 the only reason I didn't give this wrench a 5 star rating is that I have used a PW-4 and that IS a 5-star tool! At less than half the price, the PW-5 does probably 95% of what the PW-4 will do and it is very functional for me.
Changing pedals give you the leverage needed to easily remove pedals. provided you remember that one side is left hand threaded and the other is right hand thread.
