Stuck Pedals--You Need a Propane Torch
So I had a couple of stuck pedals on my rummage sale mountain bike (I wasn't the one that put them on--I know to grease them beforehand). After trying WD-40, PB Blaster (letting it soak in over 24 hrs), beeswax, and pouring boiling water over the crank arms, nothing worked. They were stuck. Yes, I was turning them in the right direction, BTW.
I finally broke down and got a propane torch from Autozone, heated up the crank arms near the pedals, and they came off in no time flat.
I'm also able to use the propane torch for soldering copper pipes and toasting marshmallows. So I think I definitely got my money's worth.

I find if you grind 1mm off the tips, you get a nice sharp corners at the end that really grip well.

is stronger than this
That is one difference between the dura ace pedals and the rest of the line up.

Assuming "all else is equal". Meaning same alloys, same construction methods, same loading and usage, etc. Difficult to quantify in real-life situations. But from an engineering & design viewpoint of someone designing a pedal-axle from scratch in Solidworks, if you wanted the strongest design for the lowest weight, you'd make as round and as smooth an axle as possible.

Yes, I didn't have to heat them that much. I did probably put more heat on the pedals themselves where they attach to the crank arms than I would if I wanted to save the pedals. They were junk, so I just torched them a little too.
