There are currently two types of PPR pipe fittings, one is a power-assisted shear, and the other is a fast shear.
Power-assisted scissors are characterized by easier pipe cutting, but the efficiency deviates.
Quick cut is characterized by faster cutting, but requires a lot of hand strength.
As for which scissors are better, it depends on which one is more suitable for you. But no matter what kind of scissors it is, the key lies in the quality of the blades of the scissors. A good blade will cut easier and last longer.
