1. Container (Figure 1)
The container is the outer layer of the sharpener that holds the pencil shavings and it is made out of clear plastic. Not all sharpeners have a container, but the ones that do include two pieces; a top and a bottom. The container has different forms and the more commonly used one is the cylinder. The Staedtler pencil sharpener has a black oval-shaped cover on top, and a blue oval-shaped base on the bottom with dimensions of 2.8 x 2.2 x 2 inches. (Staedtler Mars, n.d.).
2. Opening (Figures 2-3)
The opening/mouth is the hole at the top of the sharpener where the pencil is inserted. It is a circle that is usually slightly larger than the pencil, and the opening narrows down into the interior part of the sharpener (refer to figure 3a and 3b). This allows the standard sized pencil to fit which would secure the pencil and refrain it from moving to ensure a sharpened point. The opening can fit up to an 8.2 mm size pencil (Pencil Sharpener, n.d.) and it partially connects to the blade (refer to figure 3c) that does the sharpening. (Kristian, n.d.).
3. Blade (Figure 4a)
The blade is the interior part of the sharpener that sharpens the pencil. It is a small rectangular piece of flat steel with one edge sharpened, and is positioned at an angle of 23o (Pencil Sharpener, n.d.) that allows the edges of the pencil to be shaved off as the pencil comes into contact with the blade in a circular motion. (Kristian, n.d.).

4. Screw (Figure 4b)
The screw is a tool that holds the blade in place with the housing of the sharpener (What parts, n.d.). More than one screw may be used depending on how the blade is positioned.
5. Housing/Body (Figure 5a)
The housing is the base that supports and hold together all the interior components of the sharpener (Kristian, n.d.) and has the dimensions of 0.7 x 1.1 x 0.5 inches (Staedtler Compact, n.d.). It is shaped like an inclined plane that allows the blade to be placed at a certain angle and is made out of metal graphite.
6. Finger Grips (Figure 5b)
The finger grips are curved in spaces located on both sides of the housing on the sharpener to provide a surface for a better grasp (What parts, n.d.). These are helpful when the sharpener does not have a container.
