When you squeeze the pliers with grippers, the tip of the pliers loses pressure. For example, when I used it to pull a very thin, short wire bristle out of a wooden wire brush, I had to squeeze the pliers to hold the wire. Barely squeezing the pliers allows you to grab the wire with the tip of the pliers, but the harder I squeezed to pull it out, the tip let go. I can live with this weird defect as long as I can use it for other, more common purposes.
