Don't be fooled by the lightweight design of these "Ripper" Bottle Openers. These openers are CNC machined from (6061 t6) aircraft bullet aluminum and then anodized and re-machined to add the silver accents. They contain a stainless steel insert that adds strength and durability to this lightweight opener. Designs are laser engraved and finger cutouts offer a cool aspect to the design and functionality. Definitely an awesome opener to own!
