Serrated Pipe Cutter and Serrated Blade Therefor

A serrated pipe cutter comprising:

• first means for manually gripping;
• second means mounted on the first means for cutting a pipe, wherein the second means defines an axially elongated cutting edge including a plurality of third means for serrating the cutting edge that are axially spaced relative to each other along the cutting edge, and a plurality of fourth means for forming non-serrated cutting edge segments that are axially spaced relative to each other along the cutting edge, wherein each of a plurality of fourth means are located between respective third means, and the third means are recessed inwardly on the elongated cutting edge relative to adjacent fourth means;
• and
• fifth means coupled to the first means for supporting the pipe and for manually gripping, wherein at least one of the first and fifth means is manually movable relative to the other for driving the elongated cutting edge of the second means into engagement with the pipe to cut the pipe.

A serrated blade defining an elongated serrated cutting edge and mountable within a serrated pipe cutter including a first handle, a second handle coupled to the first handle and defining a substantially concave recess for receiving therein a pipe to be cut, wherein at least one of the first and second handles is movable relative to the other to engage a pipe with the elongated cutting edge of the blade and cut the pipe, wherein the serrated blade defines a back edge, an elongated cutting edge located on an opposite side of the blade relative to the back edge, a first side edge extending between the back and cutting edges of the blade, a second side edge located on an opposite side of the blade relative to the first side edge, a blade body extending between the first, second, back and cutting edges of the blade, and a faceted surface tapering inwardly in a direction from the body toward the cutting edge of the blade, and wherein the elongated cutting edge defines a plurality of serrations axially spaced relative to each other along the cutting edge, and each serration defines a curvilinear serration boundary between the respective serration and the contiguous faceted surface, a substantially concave serration surface located within the curvilinear serration boundary and tapering inwardly in a direction from the body toward the cutting edge, and an axially-extending serration cutting edge, and wherein the elongated cutting edge of the blade further defines a plurality of cutting tips extending between adjacent serrations, each cutting tip defines an axially extending cutting tip edge, and each serration cutting edge is recessed inwardly on the elongated cutting edge relative to at least one contiguous cutting tip edge.
