Fidget spinners have inspired a whole new set of enthusiasts, from small children to knifemakers and everything in between. While some like a plastic spinner that they won’t have to worry about getting a little dirty, others prefer a hefty chunk of metal that satisfies in the hand. For the latter, check out the B2 from Stealth. Crafted from electroplated brass, it weighs 2.5 ounces for a solid feel. The bearing inside is an R188, which offers spin times up to 5 minutes long with some practice. The bearing can be removed with the screw cover, too.
