These blades were developed by Hock Tools
in collaboration with the faculty and staff at James Krenov's Fine-Woodworking
studio in Fort Bragg. 3 1/2" long by 3/16" thick, they won't deflect or chatter
under the toughest use. Designed specifically for the finely-tuned handmade
wooden plane, these irons are un-beatable. They come complete with chip-breaker
and assembly screw.
