Obviously we all want to make something that is pleasing to the eye and functional as a cutting tool.
The question is more towards shapes and lines. I look at lots of pictures and watch lots of YTs and many knives seem to have the same shape with respect to blade shape and what handle shape they go with. Is that something people expect?
For example, when you see a Bowie knife shape, it always has a guard. Whereas you hardly ever see a bushcraft type knife with a guard. That kind of thing. Are there reasons for this, or it more of a style question?
I don't even know if I'm asking the question correctly, but as a new knife maker, it's something I've been thinking about. Thoughts?
There absolutely ARE rules to aesthetics. This is the intention of the term. But more on that later.
Form, or the operational shape of an object, is often governed by tradition, which is itself often governed by hidebound expectations of what an object
should look like. So you get differing responses to, say, the so-called American tanto knife. Experts on traditional Japanese swords and knives will shake their heads at the angular chisel point of the tip while those who grew up looking at Cold Steel knives will say that a 17c Japanese knife is "not a tanto" because the point has a soft curve. Just look at debates about what the "original Bowie knife" looked like. It is quite the rabbit hole.
In its English use, aesthetics is a philosophical term. It is from the 18c and attempts to elicit classical sentiments for what is beautiful, or pleasing to the eye and edifying to the spirit. It is also an attempt to codify what in the visual and musical and even literary arts is in harmony with nature (or even Nature). See Hogarth's treatise on The Line of Beauty, which all knifemakers should examine, whether they heed it or not. Early Modern thinkers posit that these rules are set in nature, transcend culture, and are accessible to all educated minds. The immutability of aesthetic laws is part and parcel of Enlightenment thinking.
Now compare art of the 17h and 18c with the 19c Impressionists. What travesties Seurat, Degas, Van Gogh, and others were! And less than a century later Duchamp, Picasso, and others! Nevermind his "Nude Descending A Staircase", Marcel Duchamp signed a goddamn urinal and put it in a gallery, for crissakes! This was in 1917, only a century after Napoleon! You don't have to be a Ph.D to read the message: "I am pissing all over your aesthetics."
OK, as a former scholar of these things, I can wax on about them endlessly and you definitely don't want that. Others have written about the subject a great deal better than I ever will. So let me end with this recommendation as a Deweyite: Educate yourself as best as you can in the traditions that come before us. Visit museums (in person as much as possible, virtually when necessary) to discover what has come before our current era and understand the contexts in which they swam. Play with the ideas of those who came before and interrogate their intentions. Find out where they were stretching the boundaries of what came before them. Then make some decisions on where you want to be on the spectrum. Will you adhere to Classical lines? Will you follow Enlightenment rules of aesthetics? Will you be a Modernist? Or maybe you will be Postmodern and jumble the aesthetic rules simply to please yourself. But whatever you do, examine your motives for doing so. If you come across a sense of style that pervades your work across many pieces, you may be treading on a new set of aesthetic rules that are original to you!
As for
my take on knife aesthetics, I am particularly traditional in my tastes: Scandinavian knives should not have guards, tantos should have gently curving points (Lynn Thompson be damned), Bowies are ever evolving and can take a variety of forms (because, history), pocket clips belong on box cutters not Buck knives, and, for reasons not clear to me, the shape of Shirogorov knives makes me viscerally uncomfortable. To name only a few.
So yes, there are aesthetic rules, but the knife police aren't coming to arrest you for breaking them. Form often follows function, but sometimes form follows thought, and every knife is an intellectual exercise until it fills your hand and makes its first cut.
