Knipex’s new Cobra Quick Set Water Pump Pliers can be tightened around a nut using only one hand, making it a good tool for tight spaces. The top handle, which controls the lower jaw, can slide forward without any push-button unlock—so you can keep your hands at the ends of the handles and still adjust the tool. The hex jaw can easily grip round, square, flat, or hex materials, and the handles have a non-slip plastic coating. The jaw of the 10-inch-long tool has a capacity of 2 inches. Price: $36.
