Matched Chip Breaker and Blade Set, 1-3/4"W for Stanley Handplanes #3 and #5-1/4

Revive your Antique Stanley/Bailey hand plane with these premium Blade and Chipbreaker Sets. Premier quality A-2 Pinnacle/IBC blades have been matched with an innovative chipbreaker design that can give your plane performance that rivals modern high end tools. These replacement sets are over 65% thicker than the original equipment and are match-ground and serialized at the time of manufacture. Hardened O-1 Chipbreaker with precision ground edge provides superior support for the blade. These features provide for a heavier and stiffer blade which reduces vibration and chatter, leading to improved performance. Exclusively designed Chipbreaker Blade Adjustment Tabs allow thicker premium blades/chipbreakers to function in antique planes. Minor modification may be required to the plane’s mouth opening to accommodate this blade.
