A 5 mm knife edge wedding ring for men is a great way to put together your own his and hers matching ring set if the bride has a knife edge engagement ring or wedding ring herself. Crafted from 14kt gold, you can mix it up a bit by selecting from white, rose, or yellow gold color options. You can also add some extra personality by paying a little extra for brushed or hammered finish instead of opting for the standard high polished finish and can personalize it with a custom engraving.
