The plane irons forare made of 1/8" thick A2 tool steel, which means they can hold their edge longer. The iron is ground to an angle of 25 degrees. The iron is then hardened in a controlled atmosphere to Rc60-62 for wear resistance. |
What is the hardness rating of the No. 60 1/2 Sweetheart Block Plane Iron?
