The Spine Centrifugal EDC Spinner

I came up with this idea when I found myself spinning my keys on a lanyard while shopping in a grocery story. Then it hit me, a centrifugal ring spinner! It would be something that you could attach your keys or other every day carry items. Or it could be just a nice spinner and you could add a little extra weight by attaching a paracord to the end. It could be good enough on its own, but I thought that a bottle opener would be a great compliment to it. My goal is to have an EDC item that you are proud to show off and use daily. I am going to be making the Spine spinners from the choice of three .125 inch thick materials ; Stainless Steel, Bronze, and Titanium. The bearings will come with a metal shield to prevent pocket lint from going in the bearing. The I.D. of the bearing is 20mm. I am currently running a Kickstarter campaign, you can check it out at: https://www.kickstarter.com/projects/1769702738/the-spine-centrifugal-edc-spinner?ref=user_menu
