Ron Hock - Plane Iron Assemblies
These plane irons were developed by Ron Hock in collaboration with the faculty and staff at James Krenov's Fine-Woodworking studio in Fort Bragg, California. 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.
By the way, if you are ever in this neck of the woods you should call by the College of the Redwoods which is a wonderful place that has a programme of woodworking courses including short courses.
The plane irons are High Carbon Steel which is Ron Hock's personal weapon of choice when making plane irons.
