This item solves the problem of holding a KIK lock cylinder in a vise without the vise seizing up the tailpiece which needs to be free to rotate. Put your KIK cylinder inside this holder, put the whole thing in a vise, and pick your KIK lock hassle free.
There is a cutout at the back of this holder that allows for a wide variety of lock tailpieces. This is one of the best designs for a KIK holder out there.
