That doesn't look very good! I have a Wenger with pliers. Playing with them just now, I see no problem playing with them just now. But then I've never used them for their intended purpose.
However, I had a pair of Wenger scissors do this because the pivot screw was too loose. How tight is the pivot? Does it look like the spring is bent? The springs on my pliers and scissors do sail close to the edge of the handles.
