Grozer And Running Pliers
How To Use Them
As is usual with stained glass tools, there’s often a different tool for different parts of the same process. And pliers are no exception.
Here you can find out about the range of pliers, what they’re for and how to use them. They are indispensible for cutting and will soon become one of your most important stained glass tools.
Grozing or Breaker/Grozer Pliers
These are particularly useful and have two uses:
– as breaking pliers by lining up the end of the jaws along your scoreline and snapping the glass along the score line.
– or as grozers, which means using the serrated edges of the jaws to remove stubborn nubs and tidy edges during cutting. Using these will save you lots of money on grinder heads as you won’t need to grind away so much glass.
As their name suggests these are used for breaking pieces of glass off at the scoreline. You line the top of the jaw along the score and snap the glass apart. I’ve never owned a pair as the breaker/grozer pliers do this job perfectly.
Running or Cut-Running Pliers
These are indispensible, an absolute must for making stained glass.
They have an ingeniously shaped curved cushioned jaw that puts pressure on either side of the score to break the glass apart.
Simply line up the mid-point of the jaw with your score and squeeze the handle together gently.
They’re good for straight or slightly curved cuts, and for big sheets.
There are two types of running pliers – metal and plastic.
The metal ones are far more robust and have a plastic coated jaws to prevent chipping.
They also have a thumb screw adjustment to enable you to control the amount of pressure applied to the score and to accommodate thicker glass. Recommended.
The plastic ones wear out fairly quickly and sometimes bend if you’re trying to break a thick sheet. Not recommended.
Used to cut lead came, they cut through the came easily and don’t squash it like a lead knife.
