Abstract
A linecutter article, apparatus and method wherein the linecutter is mounted adjacent a shaft seal cutting line to protect the shaft seal(s). The linecutter includes an annular ring of tough, low coefficient of fricton, abrasion-resistant, ultra-high molecular weight polyethylene or its equivalent in contact with the shaft and having a sharp linecutter edge facing outwardly. The ring is tough enough to cut monofilament fishing line but flexible enough to follow shaft runout and provides an additional seal.
