Opening a KMC master link

I'd like to install this chain:





And I bought what I thought were the appropriate tools for the job. A KMC link opener and a KMC link closer:





And I think I've got the mechanics of this correct: Basically all I should have to do is squeeze each end of the silver plated link to get it unclipped.

But I tried it and it didn't work. So I'm obviously missing something. Can someone hit me with a clue bat please?

No the Plier tool is for the derailleur chain , quick links..
you have a 1/8"or Fixed gear chain twisting a screwdriver to pry the legs apart on one pin is how those open..

they've been around for Many Decades.

In your 2nd picture, the plate on the other side is not slotted at all, I don't understand this masterlink. I am used to ones that are keyholed on both plates, so when you squeeze the rollers together the plates slide opposite of each other, and the tools you show would be great for making that happen.

It looks like on this chain, the one slotted plate in the first pic is just supposed to slide off to the left, and then both pins (fixed to the other solid plate) slide out? Maybe you got the wrong tools for that kind of chain?

What kind of chain is that? With the crazy color I'm guessing a fixie/track chain? Probably somebody more knowledgeable than me will be along.

[EDIT: yup, fietsbob with his shorter sentences beat me to it!]

So, now do you want to sell those tools? (although I'm not sure who would want two separate tools when a single Park MLP-1.2 does both jobs. Also two small screwdrivers can do that job. Also a rock)

Yep thanks. A pen-sized flathead did the trick. Feel a bit foolish now but oh well!

I've always liked the rock method for removing 10 speed chain quick links. Nice contrast to expensive chain tools. No tool needed to install.

That's a sliding spring plate which holds the structural plate on the pins.

You open it by placing a flat blade screwdriver across the open end and hitting it like a chisel to slide the spring clip back. Once you move it to where your screwdriver touches the pin, it's spring back the rest of the way allowing you to slip it over the other pin. Then the plate comes straight off. Close the link the same way in reverse.
