Your brothers in law are correct. They are a tongue and groove design
but are most commonly called channellock. Slip joints are more common
type of pliers with a jaw and grips, but instead of a fixed fulcrum like
you see in things like side cutters and needle nose, they have an
adjustable fulcrum to change the width of the jaws.
