Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 114 words
A hand held meat trimming knife having a wrist strain preventing device comprising, a manually-grippable cylindrical knife body, a knife mounting extending beyond one end of said knife body, means connecting the knife mounting to the knife body, a circular knife blade drivingly mounted in said knife mounting and having a cutting action by movement along a workpiece and pressure resulting from a manually-applied downward force, and a forearm-engaging force reaction means to relieve pressure on a user's wrist including an arcuate downwardly concave elongate shield for overlying a user's forearm, and mounting means connecting said shield to said knife body including a mounting plate held to the knife body by said connecting means.
Claim 2
Dependent Claim 114 words
A hand held meat trimming knife having a wrist strain preventing device comprising, a manually-grippable cylindrical knife body, a knife mounting extending beyond one end of said knife body, means connecting the knife mounting to the knife body, a circular knife blade drivingly mounted in said knife mounting and having a cutting action by movement along a workpiece and pressure resulting from a manually-applied downward force, and a forearm-engaging force reaction means to relieve pressure on a user's wrist including an arcuate downwardly concave elongate shield for overlying a user's forearm, and mounting means connecting said shield to said knife body including a mounting plate held to the knife body by said connecting means.
Claim 3
Dependent Claim 46 words
A hand knife as defined in claim 1 wherein said mounting means comprises a pair of spaced rods to minimize the weight of the mounting means and an arm-encircling ring connected to said pair of spaced rods and positioned for selective engagement with said knife body.
Claim 4
Dependent Claim 20 words
A hand knife as defined in claim 2 wherein one end of said rods are attached to said mounting plate.
Claim 5
Dependent Claim 247 words
A hand held meat trimming knife and a wrist strain relief attachment therefor comprising, in combination, a hand-grippable cylindrical knife body with opposite front and rear ends, a knife mounting and a circular knife blade thereon positioned beyond the front end of the knife body, means interconnecting said knife mounting and said knife body to enable downward operating pressure to be exerted by the circular knife blade by a downward force manually applied to the knife body, and said attachment comprising a mounting plate, a pair of spaced-apart rods rigidly connected to said mounting plate and extending upwardly and rearwardly therefrom to overlie said knife body and extend beyond the rear end of the knife body with a space between said rods and knife body to enable positioning of a user's hand in said space for gripping said knife body, a partial ring connected to said rods and extending downwardly therefrom and of a diameter to permit a user's forearm to extend therethrough and with a lower part of the ring being under the rear end of the knife body, and a forearm-engaging downwardly concave arcuate shield rigidly connected to said spaced-apart rods to lie above a plane extending through said knife body and knife blades and having a length to extend a distance rearwardly of said partial ring and by engaging the upper part of the user's forearm provide a force reaction to said downward operating pressure and relieve pressure on the wrist of the user.
Claim 6
Dependent Claim 247 words
A hand held meat trimming knife and a wrist strain relief attachment therefor comprising, in combination, a hand-grippable cylindrical knife body with opposite front and rear ends, a knife mounting and a circular knife blade thereon positioned beyond the front end of the knife body, means interconnecting said knife mounting and said knife body to enable downward operating pressure to be exerted by the circular knife blade by a downward force manually applied to the knife body, and said attachment comprising a mounting plate, a pair of spaced-apart rods rigidly connected to said mounting plate and extending upwardly and rearwardly therefrom to overlie said knife body and extend beyond the rear end of the knife body with a space between said rods and knife body to enable positioning of a user's hand in said space for gripping said knife body, a partial ring connected to said rods and extending downwardly therefrom and of a diameter to permit a user's forearm to extend therethrough and with a lower part of the ring being under the rear end of the knife body, and a forearm-engaging downwardly concave arcuate shield rigidly connected to said spaced-apart rods to lie above a plane extending through said knife body and knife blades and having a length to extend a distance rearwardly of said partial ring and by engaging the upper part of the user's forearm provide a force reaction to said downward operating pressure and relieve pressure on the wrist of the user.
