I was working with a guy the other day and he had the coolest set of channel locks. They were spring loaded. Once you have them around the nut, they lock automatically..then to release just let go of the handles. It auto adjusted to whatever size you needed. I asked him where he got them and he said they were given to him years ago. I have been to the box stores ( I know, I know

) but I tried LeeValley tools and some specialty tool shops but they just look at me like I have six

heads.
Has anyone ever seen these before? I would love to my hands on one.
