Pictured above are the original Zipper v1 "final version prototypes" numbered 1 through 5 from December of 2021. This image was taken shortly after these were sent out to the beta-testing team in appreciation for their months-long effort to fine-tune the balisong. This grouping was never to be reuinited again. The orange/black/grey Zipper v1 was my personal Zipper #1. My designs and manufacturing techniques have advanced significantly since this time.
