As a butcher your view is definitely different then a typical cook's view, and for very good reasons. There is no question the high-hardness often associated with japanese kitchen knives is not desirable for butchering. You generally benefit from a softer, yet tougher blade steel/ heat treatment. Most of the japanese knives are geared towards vegetables, fish and poultry.
I am just a homer cook, and will admit to applying the same logic to kitchen knives that I apply to watches (i.e., I have more then three, and they generally cost a bit more then a basic Timex. 馃榿 ) I apply the same logic to cars as well; I have more then I need (2), and it is more expensive and has more crap on it then a car really needs to get from point A to point B.
There are a few knifemakers in the US who are making some 'real' butchering knives. I have very few japanese knives myself, but a decent enough collection of chef's knives, pettys, parings, etc. from knifemakers based in the US, Canada and the UK. I am a home cook, and I enjoy the benefit of knife edges staying sharp a lot longer, etc. It speeds up prep time when I get home from work, so we can eat dinner earlier.
No question a skilled butcher can break down a whole cow, pig, goat, etc. with a single 6 inch butchering knife; I had thew pleasure of watching a master butcher do just that at a butchering class last year. No need for an arsenal of knives for work like that -- just get 'er done. But sometimes it nice to have knife choices when the luxury of time allows for it.
As far as costs go, most of the knife forum members are happy to find the lastest budget performers, as they offer by far the most bang-for-the-buck. And while knives from custom makers can hold their value (and even go up in value for some), the pro cooks would rather have cheaper options that are easy to sharpen and hold the edge for a long time with minimal touch-up needed.
Damascus is definitely window dressing, and anyone who claims it makes for a better performing knife generally has drank the Kool-Aid. It is similar to the finish work that goes into some watch movements, or a waffle patterns carved into some dials (or a meteorite dial); it offers zero performance gain. And while I have no interest in owning a mass-market damascus knife, or anything made from factory-produced damascus, I have a couple damascus knives from custom makers that are highly-functional art. No real reason for commissioning them other then the custom makers are phenomenal bladesmiths, and I wanted something that represented the height of their steel-forging skills. One such knife is a scimitar made by a maker who worked as a butcher for several years, and was eager to make some butchering knives instead of the more pedestrian gyutos. It is definitely not an everyday knife for me, but I sure as heck smile whenever I break it out to portion steaks.
Before I got drawn into the world of watches, kitchen knives represented my most frivolous purchases. I definitely got a few duds over the years, but there are quite a few in my knife blocks that remind me why I gave up on the soft stainless steel knives made by Wusthoff, Henkels, etc. The speed in which I can go through a pile of onions, bell peppers, etc. is substantially higher then with those german-branded knives that I had always been led to believe were the 'best' kitchen knives you could get. Thankfully one cooking forum educated me a bit on the wonders old european carbon knives, which then led into the world of japanese-style knives. For many stopping at the old european carbons is as far as they need/ want to go, and that is still a big step up.
