It's a good idea to produce a pair of pliers with two different grippers. But this idea is still expandable. With a flat and a side more grip pliers this is particularly well suited to serve. Without locking the grippers are about 20 cm apart, which is very inconvenient when handling. Moreover, the forceps is not stable enough, so as to access a large part. When locked, the gripper apart 3 cm, which is sufficient to serve up to even eg sausages. Infinitely locking works here very badly.
