What are the parts of a craft knife?
Craft knives are simple in design A craft knife is very simple in design with only two main parts – a blade and a handle. In addition to these parts, a craft knife will also be designed with some sort of blade securing mechanism.

Blade

Craft knife blade The blade is a thin, sharp piece of metal which is mainly used for cutting, along with other applications.

Some models of craft knife are disposable and are designed with a fixed blade that cannot be removed from the handle.

Most knives have blades which can be replaced Most craft knives, however, have blades that are replaceable, meaning once the old blade has dulled it can be removed and a new blade fitted. This option means a user does not have to constantly throw a knives away when blades have worn down.
 Donkee says 'A spare blade is included with your craft knife'
Different types of blades available Different types of blades are available to accommodate for various tasks. For more information, see What are the different types of craft knife blade?

Handle

Craft knife handle designed for comfort Craft knives often have comfort grips or specially shaped handles for a comfortable grip when using the tool.

Some handles open to allow spare blades to be stored inside.

Blade securing mechanism

Craft knives have different ways of securing the blade into the handle Some sort of mechanism or device will be used to secure the blade in place during use. The type of mechanism used can vary, depending on the type and model of craft knife.
The handle secures the blade inside the handle which can split in two

Split handle

A craft knife may have a split handle with an interlock, meaning the handle can split in two, with the blade resting on a saddle. The handle is unlocked and opened by rotating a notched wheel anti-clockwise. Once opened, the blade can be removed and replaced. To secure a blade in place and lock the two sections of the handle together, the wheel is rotated in a clockwise direction.

The collet grips the blade to keep it in place

Collet

An alternative type of blade-securing mechanism is a knurled collar and collet design. When the collar is loosened (rotated anticlockwise), the collet relaxes its grip on the blade and allows it to be removed from the handle. When the collar is tightened (rotated clockwise), the collet secures its grip on the blade, locking it into place.

Some craft knives have a bayonet fitting to secure the blade

Bayonet fitting

Another common type of blade securing mechanism is a bayonet fitting, whereby the blade slides onto a fitting at the end of the handle, and clips in to place. When fitted, the slots on the blade and the handle engage, keeping the blade securely in place.
