I've always loved spinning tops from when I was very young. My first top was a wooden throw top that my dad taught me how to throw. It took a while to get the hang of it, but that memory has stayed with me ever since. Now that I'm older, I still love tops, but my tastes have also gotten older.
In comes the precision metal spinning tops. These suckers might be expensive, but are well worth it. They are tiny pieces of art that you can play with. Yes you could buy another knife to add to your collection of EDC with the amount that you spend, but you can't really play with a knife in the way you could with a top. Plus you can bring it anywhere unlike with a knife.
That being said, you should check out the Navigator by BilletSpin on Indiegogo. This is the 25th top that they've made and its a beauty of a top. The machine work on this thing is gorgeous. Reminds me of what I imagined the Golden Compass should look like.
Last bit of information, once this campaign is over, they wont be made again!
