Like our Low Angle Bench Planes, these planes all have the blade bevel up. Low Angle Block planes have the blade bedded at 12Â°. We grind a 25Â° bevel on our block plane blades. This works well in low angle planes for end grain and general purpose work. Standard angle block planes have the blade bedded at 20Â°. The bedding angle, plus the bevel angle, equal 45Â°, which is the same cutting angle as a bench plane and gives a very good finish on flat and difficult grain. Higher cutting angles will give excellent results in difficult or highly figured woods.
Serrated blades have a grind on one side of the blade. Only sharpen the grind side of the blade. Hold the sharpener at the angle that matches the original edge angle.
