Abstract: A plurality of stainless steel wires or blades extend between cylindrical end elements on a spindle and may be stressed as desired to place them under tension. The wires or blades may be straight, that is parallel to the longitudinal axis of the spindle or spiralled relative thereto, as desired. The device may be rotated by a conventional electric drill or if electrical power is not available, by a power take-off from any engine such as a stationary engine, marine engine, automobile engine or the like, via a flexible drive cable. The device scales fish with the minimum of damage to the fish and with relative safety to the operator.
