Rare wrench knife.  It is unmarked but with direct comparison to others, it was clearly made by CP Wrench Co.  The blade is full and appears to have the original edge.  It might be a prototype since there's no branding. The tip of the blade sticks out a little when closed and it is missing the spring for the wrench.  There is no hole for the spring and there's no indication that it ever had a spring.  It does have a spring for the blade and the blade has good walk and talk.  The blade is full and appears to have the original factory edge.  For reference, the C.P. Wrench Knife, manufactured by C.P. Wrench Co. of Bristol Tennessee, combined a knife and screwdriver with a quick adjusting wrench.  Both the wrench knife and the quick adjusting wrench were patented by Charles C. Fields (U.S. Patent numbers: 888795 and 706042).
