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.
Scrub planes. Scrub planes are used for the fast removal of stock (reducing the size of boards, or pieces of wood). They are relatively short and narrow and usually have thick blades to avoid flexing under pressure. Some woodworkers consider the scrub plane to be a kind of bench plane (see below). However, its design differs from bench planes in several ways and the deep, gouging cuts that it makes give it a reputation as an 'aggressive' tool, as opposed to the more graceful, rhythmic approach associated with bench planes.
