Patent ID: 8065803

Claim:
A cutting tool comprising: a housing having a forward section provided with a compartment with a forwardly extending opening, and a rearward section which may be manually gripped; a carrier disposed in said compartment, displaceable along a linear line of travel aligned with said compartment opening, between extended and retracted positions; means operatively interconnecting said housing and said carrier for biasing said carrier toward said retracted position; means operatively interconnecting said housing, and said carrier for displacing said carrier to said extended position against the biasing action of said biasing means; means operatively interconnecting said housing and said carrier for releasably retaining said carrier in said extended position; and means disposed on a forward end of said carrier for mounting a blade disposable in partially extending position through said compartment opening when said carrier is in said extended position and disposable within said compartment when said carrier is in said retracted position, wherein said carrier includes a slot disposed substantially perpendicular to said line of travel of said carrier, and said carrier displacing means includes a button mounted on said housing, displaceable along a line of travel disposed parallel to said line of travel of said carrier and having a slot disposed substantially perpendicular to said line of travel of said carrier, and a lever pivotally connected to said housing having a first arm section with a protrusion disposed in and displaceable along said slot in said carrier and a second arm section with a protrusion disposed in and displaceable along said slot in said button whereby upon displacement of said button along the line of travel thereof, said lever will pivot, correspondingly causing said carrier to displace along the line of travel thereof.
