The Titleist AP1 712 irons each feature a cast stainless steel body with a concentrated tungsten sole weight, thin steel sole plate and an advanced dual cavity multi-material design. It builds on the success and technology of the AP1 with a Tuned Feel Cavity Insert System and an elastomer/aluminum co-molded medallion in the cavity that is specifically designed to improve feel and sound. The face thickness has been reduced to provide increased stability and an excellent feel. The short irons have a traditional design with a progressively reduced blade length and a beveled topline that allows the irons to be more precise at address.
