Dual handle safety folding knife

Abstract

An improvement for a dual handle fighting knife having interlocking handles when in open position and multiple spring blades stabilization in open and closed position. The handle blade spring engagement provides for a safe, straight-forward interlocking blade position and spacing of said cutting edge engagement with said handle when in closed position.

1. A dual handle folding knife comprising, an elongated blade having a bifurcated shank portion with multiple spring engagement surfaces thereon portions spaced by an adjoining end edge extending between the shank portions, each shank portion having multiple spring engagement edge surfaces including an outside edge and an inside edge,
 a pair of elongated handle portions, each handle portion being pivotally secured to said respective blade one of the shank portions by pivots a pivot, 
 saidand each handle portionsportion having ana corresponding elongated spring plate respectively secured thereto, each inside edge engagement surface of said shank portions is at a different angle with respect to said adjoining end edge, 
 the multiple engagement surfaces of said shank portion are tapered in respect to one another, 
 each spring plate having contoured an end portion registerable on said respective opposing tapered spring engagement surfaces and said end portions registerable on said respective opposing tapered spring for engagement with the spring engagement edge surfaces of one of the bifurcated shank portions, with each end portion being substantially registerable against one of the inside edge engagement surfaces which are in equilateral alignment with said respective pivots while when the blade is in an open locked position and handle engaged against the respective outside edge when the blade is in closed close locked position, 
 a blade stop extension, wherein spaced inwardly from said shank the end portion on one of said spring plates, for spacing a cutting surface of said blade from said registering handle portion respective spring plate when the blade is in close locked position and, one of said spring plates inter-engaging attached to the corresponding one of said handle portion portions being interengaging with the other handle portion to prevent lateral movement between said handle portions when in the blade is in open locked position. 
 
     
     
       2. The dual handle folding knife set forth in  claim 1  wherein said spring plate for interengaging between said handle portions to prevent lateral movement when in in the blade is in open locked position, further comprises,
 the contoureda second end portion of one of said spring plates in, which is oppositely disposed in relation to said bifurcated shank engagement end portion isportions registerable within said adjacentcorresponding handle portion to prevent lateral movement.
