RPK 15cm Russian Prison Nail clipper switchblade knife

Vintage RPK 15cm Russian Prison Nail clipper switchblade knife. Made in USSR prisons between 1940s and 1970s to be sold, traded, given as gifts/bribes by prison officials. This automatic nail clipper has a steel frame and clippers. The saber grind blade appears to be nearly full and shiny with light scratches. The scales are white and in fair condition. The knife opens by pushing on the edge of the back scale near the blade. Releases to close the same way. The knife works well with blade tip nicely seated, good snap and tight lockup open. Missing one screw on front scale, but works fine without it. VG condition.
