A line is a mark or series of marks that connects two points. Lines commonly found on knives are the outline or profile, the grind line, the cutting edge, the spine of the blade, the front and rear of the bolster and / or guard.

A line can also be the boundary between two different Damascus patterns or the edge where two different bevels on the handle meet. Then there are temper lines found on forged knives.

One of the most confusing descriptions for knives if one is unfamiliar with the terminology of design is "clean lines". The closest analogy is "streamlined" as used on sports cars, birds of prey, dolphins, airplanes and swallows. The idea of streamlining is to permit an uninterrupted flow of air or water. On furniture, painting and sculpture the term "clean lines" means an uninterrupted flow of observation. There are no distracting features; the eyes follow the curves and planes without having to jump around to take in the entire object being viewed.

The use of lines in designing a knife

My knife designs start out as simple line drawings, much like the one below. I do not use a CAD program for design as I believe that hand and pencil is much more suited for designing an object that will be hand-held. Also, CAD gives a "perfect line" and a "perfect curve" which the trained eye can detect from a distance, and which the untrained eye instinctively rejects without being able to put a reason to it. There is no "perfect curve" in nature.

A simple fixed blade knife design, five minutes work with pencil and paper to illustrate the use of lines in designing a knife.

Besides the obvious drawing of a knife's outline, line can also be used to suggest form or shape and texture. Through the use of "line and wash" or "pen and wash" techniques the designer can give the client a much better understanding of what the completed knife will might look like than with a simple line drawing.

Here are some examples of these techniques:
