Abstract

A powered tool 1 for cutting underwater cables comprises a bifurcate body 2 with spaced first and second arms 3, 4. An anvil pin 6 can reciprocate through the first arms 3 between a first position, in which an item to be cut can be located in the body between the first and second arms, and a second position, in which it seats in the second arm 4 to trap the item within the body. A blade 9 is slidable between the arms of the body to contact the anvil pin when the anvil pin is in its second position. Movement of the anvil pin and the blade is powered using a pressurizing fluid. To prevent flow of the pressurizing fluid to power the blade prior to adequate seating of the anvil pin in the second arm, a valve (13, Fig. 5) is provided to control the flow of pressurizing fluid for operation of the blade. Actuation of the valve, preferably by a plunger (26, Fig. 5) moved synchronously with the anvil pin, is only triggered when the anvil pin has seated adequately in the second arm of the body.
