These 3/32" thick high-carbon steel blades are renowned for their improved cutting action, as they offer a substantial improvement over the inferior blades shipped as standard with so many tools
They can be honed more easily and will get sharper
All are 7" long and will fit 99.9% of Stanley and Record-style planes with no modifications other than a simple frog adjustment
They fit most non-Stanley planes based on blade width
Please note that these blades do not fit the newer Stanley "Sweetheart" planes, released in 2009
