		There are various craft blades available which can attach to a craft knife to be used for different tasks. It is important to note, however, that not all blades fit all handles, so check the blade’s compatibility with your model of handle before buying.

		General purpose blade
		A general purpose blade can be used for multiple purposes, and is recommended if you are planning on buying only one type of blade. It enables the user to perform a variety of tasks, including heavy-duty cutting on thick materials, carving, slicing and trimming.

		Fine point blade
		A fine point blade is perfect for precise and detailed cuts, due to its design. The fine, sharp point of the blade means it can be used to cut elaborate and intricate shapes without difficulty.

		Carving blade
		There are two common types of carving blade – curved and concave. A carving blade is designed with a curve to give you better control over the depth and breadth of your cuts. It is an ideal blade to be used for initial carving and shaping.

		Whittling blade
		A whittling blade is a heavy-duty blade designed for trimming rough or coarse materials. It is capable of cutting through these types of materials due to its thick yet razor-sharp blade edge, which is longer than other types of blade.

		Deburring blade
		As the name suggests, a deburring blade is ideal for deburring, the process of removing any undesired raised edges or small pieces of material that are attached to a workpiece. Along with deburring, this blade can also be used for stripping (removing a top coating or layer from a workpiece) and cutting gaskets (a rubber sheet or ring which seals the junction between two surfaces). This is due to its sharp, tapered blade edge and fine point. Its design enables users to cut clean edges and tight corners.

		Scoring blade
		A scoring blade is a delicate instrument used for cutting and scratching notches or lines into lightweight and delicate materials. Its unique blade shape allows it to easily change direction during a cut, and enables users to perform intricate and detailed cuts without tearing the material being worked on.

		Chiselling blade
		There two main types of chiselling blade – regular and angled. A regular blade can also come in light-duty and heavy-duty versions, which are smaller and larger respectively. A chiselling blade is designed with a thin profile for removing fine layers of material and creating detailed patterns in a workpiece.

		Scalpel blade
		A scalpel blade is more commonly used in medicine for surgical procedures. However, it is also popular with many craft workers for hobby and art work due to its extremely sharp and precise cutting edge. It is often distinctive from other types of blade because of its bayonet hole, which fits on to a scalpel knife handle. There are many different shapes of scalpel blade, designed for all types of cut: for example fine point, round edge, and diagonal blades.

		Swivel blade
		A swivel blade is a very small blade, which is mounted on a pivot in a swivel handle and can rotate 360 degrees. This type of blade is ideal for cutting tiny circles and intricate patterns in light-duty materials.

		Cranked blade
		A cranked blade has a bend which positions the cutting edge clear of the handle. For this reason a cranked blade is commonly used for awkward and difficult cuts, particularly in places where the knife handle would otherwise be unable to reach.
