Abstract

A device and method for cutting a downhole object, such as a slickline, wireline or tubular is described. The device comprises first (20) and second (22) cutting members each rotatably mounted within a main housing (14) and adapted for contra-rotation. In an embodiment of the invention, the device is provided with a guide assembly (24) for locating the object in a central location of the device, and cuts the object at a single location along the length of the object with a scissor action.
