Abstract
Abstract Cutting structure for scoring or cutting surfaces is disclosed. The cutting structure includes a housing having elongated sides, a blade and thumb positioning structure associated with the elongated sides. Measurement means may be positioned against the thumb positioning structure and may be held in place by the user's thumb thus providing a measured distance which may be cut. The invention further includes angled structure associated with the housing which provides a guiding surface when making angled or mitered cuts along the edge of drywall. The invention may also include a retractable measuring structure retained within the housing, a retractable blade, retaining means formed in the housing for housing spare blades and a notch for cutting rope and the like.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
82 words
Cutting structure comprising: a housing having elongated sides, a forward end, and a rearward end; a blade extendable from said forward end; and thumb positioning structure associated with said elongated sides having an upstanding, flat planar surface structured to retain measurement means thereagainst, said upstanding flat planar surface being disposed at an acute angle from the longitudinal axis of said housing, and said thumb positioning structure being located from said blade a distance to prevent contact between a thumb and said blade.
Claim 2
Dependent Claim
82 words
Cutting structure comprising: a housing having elongated sides, a forward end, and a rearward end; a blade extendable from said forward end; and thumb positioning structure associated with said elongated sides having an upstanding, flat planar surface structured to retain measurement means thereagainst, said upstanding flat planar surface being disposed at an acute angle from the longitudinal axis of said housing, and said thumb positioning structure being located from said blade a distance to prevent contact between a thumb and said blade.
Claim 3
Dependent Claim
17 words
The cutting structure of claim 1 wherein said acute angle is about sixty-degrees from said longitudinal axis.
Claim 4
Dependent Claim
33 words
The cutting structure of claim 1 wherein said forward end of said housing further includes angled structure associated therewith providing a guiding surface for executing cuts at an angle to a planar surface.
Claim 5
Dependent Claim
24 words
The cutting structure of claim 3 wherein said guiding surface is formed at a forty-five degree angle from the lateral axis of said blade.
Claim 6
Dependent Claim
14 words
The cutting structure of claim 3 wherein said blade is retractable within said housing.
Claim 7
Dependent Claim
83 words
Cutting structure comprising: a housing having elongated sides, a forward end, and a rearward end; a recess formed in either of said elongated sides, said recess being structured to provide a flat planar surface structured to receive the thumb of a user and an upstanding flat planar surface against which measuring structure is positionable, said upstanding flat planar surface being disposed at an acute angle from the longitudinal axis of said housing; and a blade extendable from said forward end of said housing.
Claim 8
Dependent Claim
83 words
Cutting structure comprising: a housing having elongated sides, a forward end, and a rearward end; a recess formed in either of said elongated sides, said recess being structured to provide a flat planar surface structured to receive the thumb of a user and an upstanding flat planar surface against which measuring structure is positionable, said upstanding flat planar surface being disposed at an acute angle from the longitudinal axis of said housing; and a blade extendable from said forward end of said housing.
Claim 9
Dependent Claim
29 words
The cutting structure of claim 6 wherein said housing further includes angled structure associated therewith providing a guiding surface for executing cuts at an angle to a planar surface.
Claim 10
Dependent Claim
43 words
The cutting structure of claim 7 further comprising measuring structure retained within said housing and positioned transverse the longitudinal axis of said housing, said measuring structure being retractable and extendable from said housing through an opening formed proximate said upstanding flat planar surface.
Claim 11
Dependent Claim
20 words
The cutting structure of claim 8 wherein said blade is slidably positioned relative to said housing and is retractable therein.
Claim 12
Dependent Claim
30 words
The cutting structure of claim 7 wherein said acute angle is sixty-degrees, and said guiding surface is formed at a forty-five degree angle from the lateral axis of said blade.
Claim 13
Dependent Claim
113 words
Cutting structure comprising: a housing having elongated sides, a forward end, and a rearward end; a blade extendable from said forward end; and thumb positioning structure associated with said elongated sides having an upstanding, flat planar surface structured to retain measurement means thereagainst, said upstanding flat planar surface being disposed at an acute angle from the longitudinal axis of said housing, and said thumb positioning structure being located from said blade a distance to prevent contact between a thumb and said blade; an opening associated with said surface; and measurement means retained within said housing transverse the longitudinal axis of said housing, said measuring structure being extendible from said housing through said opening.
Claim 14
Dependent Claim
113 words
Cutting structure comprising: a housing having elongated sides, a forward end, and a rearward end; a blade extendable from said forward end; and thumb positioning structure associated with said elongated sides having an upstanding, flat planar surface structured to retain measurement means thereagainst, said upstanding flat planar surface being disposed at an acute angle from the longitudinal axis of said housing, and said thumb positioning structure being located from said blade a distance to prevent contact between a thumb and said blade; an opening associated with said surface; and measurement means retained within said housing transverse the longitudinal axis of said housing, said measuring structure being extendible from said housing through said opening.
