What isn't great about the Knipex Pliers Wrench? They use a ratchet-like mechanism to resize and lock the pliers into different sizes, which allows for quick resizing that won't slip.
No need to loosen or tighten the handle of the wrench, just press the button and resize to one of the 17 different size settings.
These pliers are so great that nearly 200 reviewers on Amazon gave the wrench a whopping 4.9/5 stars. This means of the 200, there were only 2 1-star ratings.
(One of ratings was simply "i don't like it". Yeah.)
