You can see from this video that the tapping method is extremely useful in certain circumstances.
But what about the times that it’s not the best choice of technique?
The tapping method is not good for:
1. Routine cutting and breaking.
It is far better to use your thumbs or either cut running or grozer/breaker pliers than to resort to tapping all the time.
This is because tapping will create an uneven edge that will then need grozing or grinding.
2. Very narrow strips.
It is difficult to use the tapping method when the score is very close to the edge of the glass as you can easily break the strip by a misplaced tap.
You would be better off using the breaking pliers to snap and pull a strip apart.
