Review on Oumers Bike Link Plier + Chain Breaker Splitter + 6 Pairs Bicycle Missing Link + Chain Plier Quick Link Opener Remover Plier | Professional Bike Chain Repair Tool Kit for 6/7/8/9/10 Speed Chains Repair by Daniel Shivashankar

They are perfect, the rubberized handle and the wide turning knob make all the difference in the world. If someone had taken the time and properly aligned the button with the chain link, breaking the actual pin needed to separate the chain link would not have been a problem. Otherwise, you will find yourself using extra strength and force and eventually breaking the pin you need the most. Be careful, set it up and it will work effortlessly. Definitely worth it
