This screw type Chain Tool is a heavy duty chain breaker that will break almost any size chain with ease. With its adjustable backstop you can be assured that you will get it right every time.
I'm giving this four stars without even using it yet. The build quality is top notch for the $10 I paid for it. If I can get replacement push pins for it through price point it's a five star. And if the steel is semi hardened and it lasts the it's a six plus out of five stars. How do you beat a tool that works and is $10. Years ago I bought a titanium multi tool for a pack that weighed almost nothing . It cost me about $40 in 1997 . It wouldn't break a chain and all the tools except the standard screwdriver weren't even functional.
