A big part of a chipbreaker's function is to dampen vibration, but chipbreakers on most metal bench planes are usually quite thin. These improved chipbreakers are machined and ground as opposed to the usual pressing. A full 3.2mm(1/8") thick with a 0.4mm(.015") lip ground at a 1° angle to provide excellent contact between the leading edge of the chipbreaker and the blade. They are very solid and each is supplied with the chipbreaker screw. All Lie-Nielsen planes from 2003 onwards will already be fitted with one of these chip breakers. Why not upgrade your existing Record or Stanley plane and enhance its performance?

Ideal UpgradeI've used Clifton two-piece chip breaker replacements on several planes and they are good, especially for a quick edge touch-up without having to reset the chip breaker. BUT having now used two Lie-Neison versions I will not be going back to Clifton. Very nicely made and need a minimum of extra work to make supreme. I would recommend smoothing the blade mating face a little more and further polishing the back just behind the edge if you are aiming for your ultimate plane tuning. Combine with a LN or similar iron and proper sorting of the frog, sole, etc. and you will have a superb set-up.
