HEAVY METAL
Blue Knuckle Designs uses metals like Argentium Sterling Silver, Bronze, and Copper. Our patent-pending T-Bar design allows the leather bands to be interchangeable for a truly comfortable fit. Since 2016, we have engineered the hell out of these bracelets. From testing many different types of leathers on over hundreds of prototypes, and adding stretch compensation capability to the leather, to optimizing the metal bracelet head arch for maximum ergonomic comfort, and even testing different button types to assure the best pull strength and ensuring a reliability of at least 5,000 attachments and removals. We believe we’ve killed it with our designs and style. Not to mention, we aren’t shy with the amount of metal that you’re going to get. Unlike other jewelry makers, we give you your money’s worth!
