Knipex TwinGrip
Score: 88/100Rankings
The Knipex TwinGrip is a versatile slip joint plier featuring unique front and side gripping capabilities, designed for handling pipes, nuts, and stripped screws in confined spaces. It utilizes a durable box joint, push-button adjustment, and induction-hardened teeth to provide maximum grip on round, square, and hex materials. Best suited for mechanics and plumbers dealing with stripped or worn screws/bolts in tight areas like engine bays.
The Channellock 424 is a compact, 4.5-inch straight jaw tongue-and-groove plier designed for precise gripping in tight spaces. It features a PermaLock fastener and laser-hardened teeth, making it ideal for small-scale mechanical and plumbing tasks. However, its limited jaw capacity makes it unsuitable for larger objects or heavy-duty work.
