An apparatus is for cutting a line extending from a floating vessel having a deck. The apparatus includes: two guide pins configured to move between a retracted position and an extended position, wherein a distance between the guide pins, in an extended position, is spanned by a spacer, the spacer forming a reaction surface; a cutting device mounted between the two guide pins, the cutting device being configured to move between a retracted position and an extended position; wherein the cutting device is arranged to perform a direct cut of the line against the reaction surface without holding the line prior to cutting such that the line may be cut directly independently of the orientation of the line.

A method and apparatus for efficiently dismantling hard disk drives, including a holder assembly to clamp a hard disk drive, a scanner that reads identification information of the hard disk drive. A chain conveyor belt indexes the hard disk drive to a position at which a logic board of the hard disk drive is peeled off and dropped into a bin, and to a position at which a lid of the hard disk drive is separated from a housing by way of a wedge, and indexes to a punch position at which magnets are punched in a direction from the logic board side of the hard disk drive. By separating and disposing the logic board and the lid, each hard disk drive is efficiently and securely dismantled.

A cable cutter includes stationary and moveable clamps, each comprising a respective pivot opening and a cutting edge spaced from the pivot opening. A pivot joint connects the clamps to allow the movable clamp to pivot about a pivot axis relative to the stationary clamp. The pivot joint includes a threaded connector having a head and a shank extending from the head along the pivot axis through the pivot openings in the clamps. A collar has opposing faces and an opening extending through the collar. A nut is threaded on the shank and the clamps are sandwiched between the head and the collar with the head adjacent one of the clamps. The collar is engaged to rotate with the shank the about the pivot axis.

A cutting tool includes a housing, a head assembly disposed on the housing and carrying a first blade. A cam drive mechanism is disposed within the housing. The cam drive mechanism carries a second blade opposed to the first blade. A motor drives the cam drive mechanism. A battery pack is electrically connected to the motor. The cam drive mechanism moves the second blade towards the first blade, so that a wire disposed between the first and second blades receives a cutting force of less than 12 kiloNewton. The cam drive mechanism may include a spindle driven by the motor, a radial cam fixed to the spindle, a roller assembly contacting the radial cam, and a shuttle connected to the roller assembly, the shuttle being movable in a reciprocating motion and carrying the second blade.
