Lie-Nielsen Chipbreakers

A big part of a chipbreaker's function is to dampen vibration, but chipbreakers on metal bench planes are usually quite thin. Traditional wooden planes, infill planes and Japanese planes typically have much thicker chipbreakers (as well as thicker blades).

In 1998, Lie-Nielsen redesigned the traditional chipbreaker. They made them thicker, with 1/8" High Carbon Tool Steel, and created a .015" lip ground at a 2° angle, which provides excellent contact between the leading edge of the chipbreaker and the blade.

Lie-Nielsen chipbreakers are designed specifically for their tools. It is possible that they may fit some original Stanley or Record planes, but critical dimensions of these and other maker's tools have varied over the years.
