It is an increase in purchase of the same tool. It is a point of being able to crimp several kinds of terminals with one pliers. You do not need to carry pliers with each terminal size. I think that the end of the handle is warped to "Ha" in order to make it easier to apply force, but I think that it is difficult to grasp to the person with small hands. Like Nicif, if you have a straight shape, you can crimp with one hand, so I think that efficiency will improve.
