Duckbills and a hook tool, or diags on the the bigger ones. Rarely ever need to resort to a hammer and diags to get one out.

I use this!!!
Is that the intent for that tool? Never seen one before. Every time I get one that's too stuck it seems it is also hidden deep out of sight and reach where only water and rust have easy access.
Dikes are what I use too. I usually have them out anyways and its one less specialty tool I need to reach for.
I do have that snap on tool as well. Its for really thick ones to hook the eye, then either grip to pull or hit the "L" with a hammer.

I have a snap on, tool that looks like a screw driver with a hook on it. I use it for many things.

I believe it's called a seal puller or seal hook. Its original intent would be to pull seals.

Is a cotter pin over there what we call a split pin? A pair of pliers have always served me well for removing those, if so.

Yes Split pin is what we call them, Cotter pins is the American name.
I use pliers to get them out but I do have one of those pick type tools as well, which does work and is quite useful for other things as well.

I have a pair of those and it works fine if you have the access space to use the tool.

I use the Wilde cotter pin tools. They work pretty good. One is 6" or 7" the other is 12" I think.

Sure is, I use one too..... Snap-on S9094B item 'E' HERE
The hook goes in the Eye of the pin and then you smack it with a hammer. Works great

I am going to be picking up one of those bigger snap on ones. Looks like just the ticket for bigger pins in dirty farm equipment.

I usually go at the small / medium ones first with a cotter pin puller or vice grips, especially the latter on larger ones, but if they want to be a real PITA, I go big...

I have an older CM Cotter pin puller made by Western Forge. It looks like a scratch awl with a bent end. It's always worked for me

We had them when I was in the Air-Force. Yes, their proper nomenclature was "Cotter-Key Extractor". We called them "The ****'s ****".

old school:
one end is pointy. other end is flat - like a slotted screwdriver blade.
thanks for reminding me I need to grab one of the Wilde models from Bowers:

We always used them for popping out pinion seals but it is in fact listed in the snap on catalog as cotter pin puller.

Thought I'd post a better photo of the bends and taper on the ends of the snap-on cotter pin pullers. It seems the deeper you get the tip into the loop the more leverage you gain. All those little bends in the tip really work well to give you added leverage. As you progress the tip gets thicker allowing you to really apply a lot of force. It's a tool that just works.
The one on the left is a Mac but I always go for the S-O.

I'm not getting the whole diagonal cutter thing? What do you guys do with those? Cut the cotter pin out?
I use pliers to unbend the bent end and then either the same pliers to pull out the pin or my cotter pin puller tool.

Hmm, I don't recall calling them by that nick name, just cotter-key extractor. What was your AFS?We had them when I was in the Air-Force. Yes, their proper nomenclature was "Cotter-Key Extractor". We called them "The ****'s ****".
