The Steelhead is the toughest most durable design on our website. This design is very unique. It is made from CrystalTi aka Crystallized Titanium. This material is actually grown. It is actual metal crystals before it is processed to a usable form for our rings. The Black Titanium is actually a Titanium/Zirconium mixed metal. When it is heat treated the metal becomes black creating a ceramic coating on the outside. This coating is very scratch resistant. I named this design “The Steelhead” well because I love to fish and also the pattern reminds me of Salmon, Steelhead and Trout. The in this photo is 9mm wide. Sized 6-9.5 will be 8.5 mm wide and 10 on up 9mm. Please see in my sizing tab for proper sizing.
