Locally 3-D printed "Butter" Fly knife.  RED  

Rounded, unsharpened and safe 3 1/2" blade.  8 1/4" open.  41/2" closed. 1/2" thick.  Made of PLA plastic.   

  Consider this an inexpensive trainer or a fidget toy.  Just a tad stiff when new, but breaks in and flips freely.  At this price,  whatcha got to lose?
