Abstract: Cutting devices and associated methods are described. In one aspect, a cutting device includes an annular support body defining an axial space into which a pipe to be cut can be inserted, the body formed of a rigid material and including a blade-bearing portion and a non-blade-bearing portion, wherein the blade-bearing portion is secured to the non-blade-bearing portion by a hinge mechanism allowing the two portions to be movable between an open position in which a pipe can be inserted, and a closed position in which the pipe is engaged by the body, wherein a part of the blade-bearing portion spaced from the hinge mechanism includes a blade that protrudes radially inwards of the body, such that in use the urging of the two portions towards the closed position urges the pipe against the blade so that rotation of the cutting device around the pipe cuts the pipe.

Abstract: A cutting device for cutting a pipe of a set diameter comprises an annular support body defining an axial space into which a pipe to be cut can be inserted. The annular support body is formed of a rigid material and comprises a blade-bearing portion and a non-blade-bearing portion. The blade-bearing portion is secured to the non-blade-bearing portion by a hinge mechanism allowing the two portions to be movable between an open position, in which the pipe can be inserted and removed from the body, and a closed position, in which the pipe, once inserted, is engaged by and axially aligned with the annular support body. A part of the blade-bearing portion spaced from the hinge mechanism comprises a blade that protrudes radially inwards of the annular body, such that in use the urging of the two portions towards the closed position urges the pipe against the blade so that rotation of the cutting device around the pipe cuts the pipe.
