Repairable for Long Life

The clear rubber cushions tend to split and fall off of the jaws over years of use, but we have repaired the jaws of our tools merely by wrapping in several layers of electrical tape, which we have also used to replace plastic grips on hand tools. Artist Joe Moorman proudly owns and uses several of his grandfather’s hand tools that have had their broken center bolts replaced with ordinary bolts and a locking nut. These sort of common-sense repairs save you money and keep perfectly usable tools out the landfill. There is no reason a single-pair of these pliers could not last a lifetime and beyond with simple repairs.

Do You Need This Tool?

If you are snapping apart long straight scores in a piece of stained glass, then no, you don’t. You can easily snap apart a straight score by placing a straight object under the score and pressing down on the glass on both sides of the score with your gloved hands. The straight object can be a pencil or an uncooked stick of spaghetti. Snapping these straight lines is simple and easy. What is difficult is snapping a curved score. For snapping curved pieces of stained glass apart, Running Pliers are needed.
