Stainless Steel, reusable 170mm ring cutter.
Constructed from stainless steel, these box-joint constructed cutting pliers allow you to remove rings using a built-in stainless steel circular saw blade.
It fits well into the protective guard that is cut into the facing jaw; therefore protecting the tool and the blade during use.
Carefully slide the lower jaw between the ring and finger, then turn the handle while the blade will cut through your ring in seconds.
