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, we redesigned the traditional chipbreaker (shown rear left). We made them thicker, with 1/8" High Carbon Tool Steel, and created a .015" lip ground at a 1° angle, which provides excellent contact between the leading edge of the chipbreaker and the blade. Both improvements have been widely imitated by other toolmakers.
