The CavPro^® KPA with high-impact asymmetrical plastic blades features a unique take-down ferrule that can be positioned at 60° left, right, or inline for better control. Grooves on the ferrule prevent the build-up of sand and debris, maintaining a tight, trouble-free fit. The rubber-wrapped black anodized aluminum shaft is oval shaped at normal hand position. Oval shaft dimension: 1-1/8" W x 1-1/4" D.
