    摘要： There is disclosed an underwater tool (5; 205; 305) comprising a grabber arrangement (15; 215; 315) and a cutter arrangement (20; 220; 320) which are connected together. The grabber arrangement (15; 215; 315) comprises a plurality of grabber elements (30; 230; 330) disposed on first and second sides (35a; 235a; 335a; 35b; 235b; 335b) of the tool (5; 205; 305). The cutter arrangement (10; 205; 305) a cutter slot (75; 275; 375), an anvil (80; 280; 380) movable to close the slot comprises an anvil (80; 280; 380) and a cutter blade (90; 290'; 390). In use, a cable (10; 210; 310) is held by the grabber arrangement, and thereby moved into the slot (75; 275; 375) which is then closed by the anvil (80; 280; 380) so as to entrap the cable (10; 210; 310) within the slot (75; 275; 375). The cutter blade 90; 290; 390) is then driven against the anvil (80; 280; 380) so as to cut the cable (10; 210; 310).
