Claim 3

A tool according to claim 1 wherein said retractable stop member is spring-loaded for normally entering said notch when said notch is placed in registry therewith and further including release means mounted on said handle and operatively coupled with said retractable stop member for selectively releasing said retractable stop member from said notch.

Claim 4

A tool according to claim 2 wherein said spring-loaded stop member is arranged for elastically yielding to said tang during insertion thereof into said slot until said notch is in registry with said stop member.

Claim 5

A tool according to claim 1 or claim 3 and further including pin means in said storage compartment located for removably pivotally receiving said notch, whereby said blade is rotatable about the pivotally engaged notch and pin means to a storage position substantially within said compartment, and wherein said first releasable locking means includes elastically deformable means mounted in said storage compartment.

Claim 6

A tool according to claim 4 wherein said elastically deformable means comprises a leaf spring spaced apart from said pin means for engaging a leading edge portion of said tool blade tang for fulcruming said tool blade about said pivotally engaged notch and pin for insertion into and removal from said storage compartment, respectively.

Claim 7

A tool according to claim 1 and further including lanyard means comprising a tang portion dimensioned similarly to said at least one tool blade tang portion for releasable locking engagement with said second compartment and carrying cord means coupled with said lanyard tang.

Claim 8

A tool according to claim 1 wherein three tool blades are provided, each having substantially identical cooperating locking means, and wherein three storage compartments are provided in said handle for receiving each of said three tool blades.

Claim 9

A tool accommodating interchangeable tool blades comprising: a handle for receiving one tool blade in a working position and at least one tool blade in a storage position, a first compartment defined in said handle for receiving said at least one tool blade in a storage position and including releasable locking means for releasably locking said at least one tool blade in a storage position; a second compartment in said handle for receiving said one tool blade in a working position and including second releasable locking means for releasably locking said tool blade in said working position; at least one tool blade including cooperating locking means for releasably locking with either of the first or second releasable locking means for releasably holding the tool blade assembled with the tool handle in either of the working position or storage position; and lanyard means comprising a tang portion dimensioned similarly to said at least one tool blade tang portion for releasable locking engagement with said second compartment and carrying cord means coupled with said tang portion.

Claim 10

A tool accommodating interchangeable tool blades comprising: a handle for receiving one tool blade in a working position and at least one tool blade in a storage position, a first compartment defined in said handle for receiving said at least one tool blade in a storage position and including releasable locking means for releasably locking said at least one tool blade in a storage position; a second compartment in said handle for receiving said one tool blade in a working position and including second releasable locking means for releasably locking said tool blade in said working position; at least one tool blade including cooperating locking means for releasably locking with either of the first or second releasable locking means for releasably holding the tool blade assembled with the tool handle in either of the working position or storage position; and lanyard means comprising a tang portion dimensioned similarly to said at least one tool blade tang portion for releasable locking engagement with said second compartment and carrying cord means coupled with said tang portion.

Claim 11

A tool accomodating removable and interchangeable tool blades comprising: a handle capable of simultaneously receiving one tool blade in a working position and at least one tool blade in a storage position, a first compartment defined in said handle for receiving said at least one tool blade in a storage position and including releasable locking means for removably and releasably locking said at least one tool blade in a storage position, a second compartment in said handle for receiving said one tool blade in a working position and including second releasable locking means for removably and releasably locking said tool blade in said working position, and at least one tool blade including cooperating locking means for removably and releasably locking with either of the first or second releasable locking means for releasably holding the tool blade removably assembled with the tool handle in either of the working position or storage position; wherein said second compartment comprises a slot; wherein said at least one tool blade comprises a working portion and a tang dimensioned to removably, slidably interfit with said slot; wherein said slot and said tang are substantially rectangular; wherein said cooperating locking means comprises a notch formed in one side of said rectangular tang and said releasable locking means comprises a retractable stop member in one side of said slot for releasably locking with said notch when said tang is positioned so as to place said notch in registry with said retractable stop member; and further including pin means in said storage compartment located for removably pivotally receiving said notch, whereby said blade is rotatable about the pivotally engaged notch and pin means to a storage position substantially within said compartment, and wherein said first releasable locking means includes elastically deformable means mounted in said storage compartment.

Claim 12

A tool accomodating removable and interchangeable tool blades comprising: a handle capable of simultaneously receiving one tool blade in a working position and at least one tool blade in a storage position, a first compartment defined in said handle for receiving said at least one tool blade in a storage position and including releasable locking means for removably and releasably locking said at least one tool blade in a storage position, a second compartment in said handle for receiving said one tool blade in a working position and including second releasable locking means for removably and releasably locking said tool blade in said working position, and at least one tool blade including cooperating locking means for removably and releasably locking with either of the first or second releasable locking means for releasably holding the tool blade removably assembled with the tool handle in either of the working position or storage position; wherein said second compartment comprises a slot; wherein said at least one tool blade comprises a working portion and a tang dimensioned to removably, slidably interfit with said slot; wherein said slot and said tang are substantially rectangular; wherein said cooperating locking means comprises a notch formed in one side of said rectangular tang and said releasable locking means comprises a retractable stop member in one side of said slot for releasably locking with said notch when said tang is positioned so as to place said notch in registry with said retractable stop member; and further including pin means in said storage compartment located for removably pivotally receiving said notch, whereby said blade is rotatable about the pivotally engaged notch and pin means to a storage position substantially within said compartment, and wherein said first releasable locking means includes elastically deformable means mounted in said storage compartment.
