I recently saw four specialized key adjusting pliers designed and made by Gordon Palmer, which got the (random) names of A, B, C and D. There aren't many places to buy key adjusting pliers, and I don't know any so specific. I have one from Boehm (expensive and somewhat useful). Allied and Ferree's each has one type. I also saw the Marius Kowalski (sp?) key pliers. None impressed me like the ones Gordom made which seem far more specific and useful. Types A, B and C are made from "blanks" (normal big pliers with enough metal to carve the right shape) and type D is a modified Ferree's key pliers.
So far I only made type C, made from a relatively small pair of (mostly) flat nose pliers. Here is a link to show how they were made http://www.flickr.com/photos/53728008@N00/sets/72157627890355994/
You can the shape in the photos though it's not really possible to see all the little but critical shapes and measurements of the tips. This was all done with a micromotor.
I will probably make the other types eventually.
