UK DESIGNED GRIPS FIT YOUR HAND BETTER THAN ANY OTHER Sabre designed the newly released Trident Grips specifically for cartridge needles. Real comfort has arrived. These new cartridge grips, which we have found to work with the same excellence as our Ultra cartridge grips but with more comfort because of the ergonomic designs and an extra wide diameter. That’s something you don’t get with all tattoo grips. The Trident has a Triangular shape with a 1 1/4″ (30mm) size grip. In fact, Sabre registered the designs, which means they really are in a class all of their own.
