Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 273 words
A knife holder comprising a generally solid block member defined by exterior planes including a face plane and having a longitudinal axis perpendicular to said face plane wherein said block has formed therein a plurality of elongated slots for storing and protecting knife blades wherein each said slot is defined by a separate pair of substantially parallel closely spaced side walls extending a substantial distance into said block member parallel to said longitudinal axis wherein each of said slot defining walls has an edge in said face plane whereby a knife blade can be inserted into said block member through one of said slots in said face plane thereof a plurality of spaced divider grooves formed in at least one side wall of each of said slots and wherein each said divider groove has an edge in said face plane a plurality of slot dividers, each formed to be slideably insertable into and removable from a slot at a selected divider groove, each of said dividers having a width that spans the distance between the walls defining a slot and a length which permits each said divider to extend from said face plane into said block a substantial distance, said divider including a portion which registers in a divider groove when said divider is inserted into said block at a divider groove whereby each of said slots is divisible into a plurality of knife blade storing and protecting pockets wherein the number of said pockets formed from each slot and the size knife blade which can be inserted into a pocket is determined by the particular divider grooves into which dividers are inserted.
Claim 2
Dependent Claim 273 words
A knife holder comprising a generally solid block member defined by exterior planes including a face plane and having a longitudinal axis perpendicular to said face plane wherein said block has formed therein a plurality of elongated slots for storing and protecting knife blades wherein each said slot is defined by a separate pair of substantially parallel closely spaced side walls extending a substantial distance into said block member parallel to said longitudinal axis wherein each of said slot defining walls has an edge in said face plane whereby a knife blade can be inserted into said block member through one of said slots in said face plane thereof a plurality of spaced divider grooves formed in at least one side wall of each of said slots and wherein each said divider groove has an edge in said face plane a plurality of slot dividers, each formed to be slideably insertable into and removable from a slot at a selected divider groove, each of said dividers having a width that spans the distance between the walls defining a slot and a length which permits each said divider to extend from said face plane into said block a substantial distance, said divider including a portion which registers in a divider groove when said divider is inserted into said block at a divider groove whereby each of said slots is divisible into a plurality of knife blade storing and protecting pockets wherein the number of said pockets formed from each slot and the size knife blade which can be inserted into a pocket is determined by the particular divider grooves into which dividers are inserted.
Claim 3
Dependent Claim 41 words
The knife holder of claim 1 wherein the longitudinal axis of said block member when said block member is free-standing on a horizontal surface forms an angle of more than 30 degrees but less than 60 degrees with the horizontal surface.
Claim 4
Dependent Claim 21 words
The knife holder of claim 2 wherein said divider grooves extend a substantial distance from said face plane into said block.
Claim 5
Dependent Claim 42 words
The knife holder of claim 3 wherein all of said divider grooves extend into said block from said face plane the same distance and all of said slot dividers are of equal length and approximately the same length as said divider grooves.
Claim 6
Dependent Claim 23 words
The holder of claim 4 wherein said slots extend into said block from said face plane a greater distance than said divider grooves.
Claim 7
Dependent Claim 31 words
The knife holder of claim 2 wherein the portion of said slot divider that registers with said divider groove maintains said divider approximately parallel to said longitudinal axis of said block.
Claim 8
Dependent Claim 24 words
The knife holder of claim 2 wherein said divider grooves are defined by shallow recesses in said face plane extending transverse to said slots.
Claim 9
Dependent Claim 49 words
The knife holder of claim 7 wherein said slot dividers are further defined as having an end member which registers with a recess when said divider is inserted into a slot adjacent a divider groove whereby said divider is maintained at an angle generally parallel to said longitudinal axis.
Claim 10
Dependent Claim 37 words
The knife holder of claim 7 wherein each of said recesses extends from each side of a slot at a divider groove location and said divider end member forms a "T" with the rest of said divider.
Claim 11
Dependent Claim 48 words
The knife holder of claim 1 wherein said divider grooves are further defined as extending from said face plane a substantial distance into said block member and formed in both side walls of said slots in opposing relationship to form groove pairs that extend transversely to said slot.
