What types of Surform blades are there?

	Blades of various shapes and sizes are available for various types of surface finishing tools.
Flat
	A flat blade can also be called a standard surform blade. It has a long, straight shape, which means it is often used to work on flat surfaces. Some versions have side teeth along one edge, which are useful when shaving corners and working around edges. It can be used on a range of materials including wood, plaster, PVC, soft metals and fiberglass. It is typically used as a general purpose blade and is ideal for initial and quick removal of material from a workpiece.
	This type of blade is usually seen on a flat surface or a flat file. The flat blade is 250 mm (approx. 10 inches) long.
Round
	The round type is a round shaped blade - it looks like a pipe with holes in it. It can be used on many materials such as wood, soft metals, plastics and laminates. This is the ideal type for creating narrow curves in a workpiece, or for sculpting or enlarging holes within an object.
	This type of blade is designed to be used as part of a Surform round file. The round blade is usually 250 mm (approx. 10 inches) long.
Semicircular
	A semi-circular blade is a cross between a flat and a round type, having a rounded curve on its surface. It is versatile and can be used on a variety of materials, including working with fiberglass and removing filler from surfaces.
	It is ideal for quickly removing material from a workpiece as well as shaping curved surfaces. A semi-circular blade is especially useful for working on concave surfaces, as the curvature of the blade can match the shape of the material. The semi-circular blade is usually 250 mm (approx. 10 inches) long.
good cut
	A fine cut surform blade is similar in appearance to a flat blade, but has slightly smaller perforated holes than other types. It is designed to create a smoother surface on the workpiece and is used in particular for hardwoods, endgrain (grain at the ends of a piece of wood) and some soft metals.
	This type of blade is typically used in a surform plane or surform file. The fine cutting blade is available in two sizes: 250 mm (approx. 10 inches) and 140 mm (approx. 5.5 inches) in length.
razor
	A razor blade is much smaller than other types of blades, which means that it is usually used to treat small or awkward places where larger blades might not fit. It is designed with side teeth along one edge which means it is ideal for cutting into tight corners. It is also an ideal blade for stripping paint and smoothing putty.
	This type of blade can be found on the Surform shaving tool. A razor blade is usually 60 mm (approximately 2.5 inches) long.
