Many rod cutters have a double action design which delivers power to the cutter and gives the surgeon better control and a smooth and easy cutting action. Our gSilicone Rod Shears provide a clean cut without burrs or sharp edges for rod diameters 4.5mm [.177″], 5.5mm [.217″], and 6.35mm [1/4″], and also have biocompatible silicone handles for a comfortable and secure grip. Select a rod cutter based on the rod diameter being cut and do not exceed the maximum capacity rod diameter marked on the cutter.
