An actuator is slidingly engaged with the chassis to reposition the blade between the retracted and deployed positions. A stop pin is connected to the blade. An end of the stop pin extends a predetermined distance from the blade to engage with the surface defined by the chassis when the blade is in the deployed position to prevent movement of the blade with respect to the chassis. ## Claims ### Claim 1 A pocket knife, comprising: a chassis; a surface defined by the chassis; a blade having a fully retracted position in which the blade is inside of the chassis and a fully deployed position in which at least a portion of the blade is outside of the chassis; an actuator slidingly engaged with the chassis and configured to reposition the blade between the fully retracted and fully deployed positions; a stop pin connected to the blade; and an end of the stop pin extends a predetermined distance from the blade to engage with the surface defined by the chassis when the blade is in the fully deployed position to prevent movement of the blade with respect to the chassis. ### Claim 2 (depends on 1) The pocket knife as in claim 1, wherein the surface defined by the chassis is curved. ### Claim 3 (depends on 1) The pocket knife as in claim 1, wherein the end of the stop pin is tapered and the surface defined by the chassis is angled to match the tapered end of the stop pin. ### Claim 4 (depends on 1) The pocket knife as in claim 1, further comprising a means for adjusting the predetermined distance that the end of the stop pin extends from the blade. ### Claim 5 (depends on 1) The pocket knife as in claim 1, wherein the stop pin is in threaded engagement with the blade. ### Claim 6 (depends on 1) The pocket knife as in claim 1, further comprising a set screw in threaded engagement with the blade to lock the end of the stop pin at the predetermined distance from the blade. ### Claim 7 (depends on 1) The pocket knife as in claim 1, further comprising a lock pivotally connected to the chassis and engaged with the blade in the fully deployed position to lock the blade in the fully deployed position. ### Claim 8 A pocket knife, comprising: a chassis; a blade having a retracted position in which the blade is inside of the chassis and a deployed position in which at least a portion of the blade is outside of the chassis; an actuator slidingly engaged with the chassis and configured to reposition the blade between the retracted and deployed positions; a lock pivotally connected to the chassis and engaged with the blade in the deployed position to lock the blade in the deployed position; a stop pin connected to the blade; and an end of the stop pin extends a predetermined distance from the blade to engage with the chassis when the blade is in the deployed position to prevent movement of the blade with respect to the chassis. ### Claim 9 (depends on 8) The pocket knife as in claim 8, wherein the stop pin is in threaded engagement with the blade. ### Claim 10 (depends on 8) The pocket knife as in claim 8, further comprising a means for adjusting the predetermined distance that the end of the stop pin extends from the blade. ### Claim 11 (depends on 8) The pocket knife as in claim 8, further comprising a set screw in threaded engagement with the blade to lock the end of the stop pin at the predetermined distance from the blade. ### Claim 12 (depends on 8) The pocket knife as in claim 8, wherein the chassis defines a curved surface, and the engagement between the end of the stop pin and the chassis when the blade is in the deployed position to prevent movement of the blade with respect to the chassis is between the end of the stop pin and the curved surface defined by the chassis. ### Claim 13 (depends on 12) The pocket knife as in claim 12, wherein the end of the stop pin is tapered and the curved surface defined by the chassis is angled to match the tapered end of the stop pin. ### Claim 14 A pocket knife, comprising: a chassis; a blade having a fully retracted position in which the blade is inside of the chassis and a fully deployed position in which at least a portion of the blade is outside of the chassis; an actuator slidingly engaged with the chassis and configured to reposition the blade between the fully retracted and fully deployed positions; a means for preventing movement of the blade with respect to the chassis when the blade is in the fully deployed position. ### Claim 15 (depends on 14) The pocket knife as in claim 14, wherein the means for preventing movement of the blade with respect to the chassis when the blade is in the fully deployed position comprises a curved surface defined by the chassis. ### Claim 16 (depends on 14) The pocket knife as in claim 14, wherein the means for preventing movement of the blade with respect to the chassis when the blade is in the fully deployed position comprises a stop pin in threaded engagement with the blade. ### Claim 17 (depends on 16) The pocket knife as in claim 16, wherein an end of the stop pin extends a predetermined distance from the blade to engage with the chassis when the blade is in the fully deployed position, and further comprising means for adjusting the predetermined distance that the end of the stop pin extends from the blade. ### Claim 18 (depends on 16) The pocket knife as in claim 16, wherein an end of the stop pin extends a predetermined distance from the blade to engage with the chassis when the blade is in the fully deployed position, and further comprising a set screw in threaded engagement with the blade to lock the end of the stop pin at the predetermined distance from the blade. ### Claim 19 (depends on 14) The pocket knife as in claim 14, further comprising a lock pivotally connected to the chassis and engaged with the blade in the fully deployed position to lock the blade in the fully deployed position.
