Jimmy Sanders Color Changing Knives circa 1950: simply the best ever made

The highly desirable and scarce knife set from Jimmy Sanders with original instructions.  If you are into knives i don’t have to say much about these. Blades are clean with no rust. The set includes blk/blk, wh/wh, blak/wht and a mini knife. I have seen these sell for over $500 without the mini so this is a great value.
