Snap removal tools are used to remove snaps that have already been set. Sometimes when working we realize that a snap will need to be undone or moved (from a design change, a snap is damaged, etc.). Snap removal tools are sturdy, metal tools that will disassemble a snap so it can come free from the material it was originally joined to.
Some of these tools are hand-held and require a fair amount of force to squeeze them. Others are table-mounted, providing a bit more leverage and an easier task of pushing a lever arm to free the snap from the material.
