There are items without some strict outlines which can be rather some hint than actual contour of line icons. They're called gesture drawings. Such drawings are being widely used by experienced artists who can repeat the outlines of the object right after seeing it.
One more technique is adding some halftones and shades to the object. It's possible by using short lines and crosshatching. Dont afraid to vary their frequency and also pencil pressure.

The curves that are important for creating complex line shapes are called Bezier curves in computer graphics. These curves are real helpers in creation of the vector shapes such as line icons, different buttons etc. Computer technologies have the ability to reproduce the same designs or build new shapes based on some older ones without extra efforts and time. Another advantage is that you can easily go back to the previous adjustments with a help of the history panel.
