Lapped 25° bevel replacement blades for the apron plane, made of O1, A2 or PM-V11 tool steel
The O1 blade is 0.098" thick (nearly 25% thicker than standard 0.080" block plane blades), 1 1/4" wide and hardened to Rc58-60
For yet more beef, choose the A2 blade or the PM-V11 blade, each 1/8" thick
The 38° A2 toothed blade is for working difficult grain, especially knots; the small, square teeth leave a textured surface that can be smoothed with a scraper
