Abstract:
A hand held utility knife for cutting and trimming thin planar materials, the utility knife comprising:a) a knife body adapted for grasping in a single hand;b) at least one knife blade mounted proximate a guide end in said knife body and having a cutting direction axis;c) said guide end including a guide means for guiding said knife along an interior corner in a uniform angular relationship relative to an adjacent planar surface such that the guide means minimizes rotation of the knife body about said cutting direction axis,(d) wherein the guide means comprises at least one guide cheek defining a planar surface disposed at an angle theta relative to said knife blade such that said guide cheek is adapted to slidably engage and move parallel along an adjacent planar surface thereby ensuring that the blade cuts material at a uniform and preselected angle,(e) wherein the at least one guide cheek comprises at least two guide cheeks defining a planar surface each disposed at an angle theta relative to said knife blade such that said guide cheeks are adapted to slidably engage and move parallel along adjacent planar surfaces, thereby ensuring that the blade cuts material at a uniform and preselected angle,(f) wherein the at least two guide cheeks comprise a corner guide including first and second guide cheeks each defining a planar surface and disposed at an angle theta relative to said knife blade such that said first guide cheek is adapted to slidably engage and move parallel along a first planar surface and said second guide cheek is adapted to slidably engage and move parallel along a second planar surface thereby ensuring that the blade cuts material at a uniform and preselected angle, and(g) wherein the knife body comprises a utility end and said guide end, said the utility end including a second knife blade, such that the at least one knife blade mounted proximate the guide end is used for cutting and trimming in corners and the second knife blade mounted in said utility end is used for conventional utility knife cutting and trimming operations.
