Let me add my not-so-humble opinion here...
Sharpening knives '
can be' an 'art' that is
easily learned. Or...
Sharpening knives '
can be' simply a skill... that is easily learned.
It all depends on how you approach it. Nothing more. I'll explain what I mean.
Let's start with the 'skill' side. All we need is a simple guided sharpening device and its own stones. 15 minutes later and a monkey can have a shaving sharp edge. Read the manual first (hmmm.... that may fall into the 'art' catagory...) decide on the edge angle you want... set the screws, and scrub the blade with the stones quickly. This can be done while watching Monday Night Football. Before the first quarter is finished, the blade is shaving sharp.
Next, look at the free-hand sharpening on 2-3 stones approach. Once again. RTFM. This goes without saying. You have to learn how to use your tools before you start to use them correctly. Then you begin to practice and develop your skills. Still doesn't take a Rembrant or Picasso to turn out a sharp edge. It just takes understanding basic geometry and practicing your skill set. 30-45 minutes and you have a shaving edge 'after' developing your skills.
Lastly... Art. And we have the person who has purchased 27 different stones (and perhaps given each its own pet name,) sets up a quiet table away from all distractions, maybe even plays some quiet music in the background, maybe burns some incense and puts on a special apron or head band. Then sloooowly, he/she begins carving into the first stone. By the time he/she reaches the last stone, the seasons have changed. But then it's time to begin the stropping. Once again there is a progression from 3mic, 2mic, 1mic, 0.5mic 0.25mic and 0.10mic. Each of these grits, of course, needs to be done on three different substrates before moving to the next finer grit. The result is a shaving sharp edge, and it only took three days.
There is certainly a distinction between skill and art, but not necessarily a separation between them. Something can easily be both at the same time.
But perhaps most importantly, there is a very fine line between 'hobby,' and mental illness.
