Abstract

Official abstract text for this publication.

A pocket knife includes a chassis and a blade having a retracted position in which the blade is inside the chassis and a deployed position in which at least a portion of the blade is outside of the chassis. A tang of the blade has first and second legs that extend from the tang to define a recess in the tang between the first and second legs. At least a portion of the chassis extends into the recess in the tang between the first and second legs when the blade is in the retracted position.

First claim

Opening claim text (preview).

What is claimed is: 1. A pocket knife, comprising: a chassis; a blade having a retracted position in which the blade is inside the chassis and a deployed position in which at least a portion of the blade is outside of the chassis; a tang of the blade; first and second legs that extend from the tang to define a recess in the tang between the first and second legs; and a protrusion of the chassis extends into the recess in the tang between the first and second legs when the blade is in the retracted position. 2. The pocket knife as in claim 1 , further comprising an aperture through the chassis and at least a portion of the aperture overlaps the recess in the tang between the first and second legs when the blade is in the retracted position. 3. The pocket knife as in claim 1 , further comprising a front operator inside the chassis, wherein the front operator engages with the blade to move the blade to the retracted position. 4. The pocket knife as in claim 1 , further comprising a rear operator inside the chassis, wherein the rear operator engages with the blade to move the blade to the deployed position. 5. The pocket knife as in claim 1 , further comprising a front lock inside the chassis and engaged with the blade in the deployed position. 6. The pocket knife as in claim 1 , further comprising a rear lock inside the chassis and engaged with the blade in the retracted position. 7. A pocket knife, comprising: a first scale; a second scale opposed to the first scale to define a cavity between the first and second scales, a blade having a cutting edge, wherein the blade has a retracted position in which the cutting edge is between the first and second scales and a deployed position in which the cutting edge is outside of the cavity; a tang of the blade; first and second legs that extend from the tang to define a recess in the tang between the first and second legs; and a protrusion of at least one of the first scale or the second scale extends into the recess in the tang between the first and second legs when the blade is in the retracted position. 8. The pocket knife as in claim 7 , further comprising an aperture through the first and second scales and at least a portion of the aperture overlaps the recess in the tang between the first and second legs when the blade is in the retracted position. 9. The pocket knife as in claim 7 , further comprising a means for releasably connecting the first scale to the second scale and at least a portion of the means for releasably connecting the first scale to the second scale is located in the recess in the tang between the first and second legs when the blade is in the retracted position. 10. The pocket knife as in claim 7 , further comprising a front operator between the first and second scales, wherein the front operator engages with the blade to move the blade to the retracted position. 11. The pocket knife as in claim 7 , further comprising a rear operator between the first and second scales, wherein the rear operator engages with the blade to move the blade to the deployed position. 12. The pocket knife as in claim 7 , further comprising a front lock between the first and second scales and engaged with the blade in the deployed position. 13. The pocket knife as in claim 7 , further comprising a rear lock between the first and second scales and engaged with the blade in the retracted position. 14. A pocket knife, comprising: a first scale; a second scale opposed to the first scale to define a cavity between the first and second scales; a blade having a cutting edge, wherein the blade has a retracted position in which the cutting edge is between the first and second scales and a deployed position in which the cutting edge is outside of the cavity; a slider inside the cavity; a front operator inside the cavity, wherein the slider engages with the front operator to move the blade to the deployed position; a rear operator inside the cavity, wherein the slider engages with the rear operator to move the blade to the retracted position; a tang of the blade; first and second legs that extend from the tang to define a recess in the tang between the first and second legs; and a protrusion of at least one of the first scale or the second scale extends into the recess in the tang between the first and second legs when the blade is in the retracted position. 15. The pocket knife as in claim 14 , further comprising an aperture through the first and second scales and at least a portion of the aperture overlaps the recess in the tang between the first and second legs when the blade is in the retracted position. 16. The pocket knife as in claim 14 , further comprising a means for releasably connecting the first scale to the second scale and at least a portion of the means for releasably connecting the first scale to the second scale is located in the recess in the tang between the first and second legs when the blade is in the retracted position. 17. The pocket knife as in claim 14 , further comprising a front lock inside the cavity and engaged with the blade in the deployed position. 18. The pocket knife as in claim 14 , further comprising a rear lock inside the cavity and engaged with the blade in the retracted position. 19. The pocket knife as in claim 14 , further comprising a spring connecting the front operator to the rear operator inside the cavity.
