It is a truism that any tool best fits the hand of its maker.
The Hock line of Krenov-style blades was developed in collaboration with the faculty and staff at the Krenov School of Fine Woodworking in Fort Bragg, California. Made from 3/16" thick HCS (O1), they won't deflect or chatter under the toughest use. Designed specifically for finely tuned handmade wooden planes, these irons are unbeatable.
Bevel is 30°. They are available with or without chip breakers, and are also available as radiused blade sets.
