I worded this question a specific way, and some answered the question, and some didn't.
I realize that this is a general knife discussion, it says so right up top in the little blue letters. Interestingly enough, for a public and open forum, no true newbies posted. Thus far it has been veterans of this forum, and some very experienced makers weighing in. So at the very least, I am getting responses from the intended contributors.
I asked at what point is critique requested on this forum, and based upon the responses, I think it breaks down into two different types of responses:
1) At no point is direct critique requested on this forum, if you have something unpleasant to say, take it offline, so that this does not become public humiliation, or an approximation of such. (specific example, my posting on the Russian Guy's Damascus Dagger)
OR
2) Critique is all right, but point out the good stuff, and gently mention the bad, or couch it by saying that you realize that this is your opinion. If it starts to look personal, the critic, it's gonna get jumped on (specific example, the Whole Bob T. thread), and shut down eventually.
If I am correct, than I can live with that, and will conduct myself accordingly in the future. At least some discussion occured, and I thought that it was productive.
Of course you have to handle a knife to truly appreciate and judge it. It's the same as asking someone if they like the way a meal tastes before they have eaten it. Without eating it, you only have your eyes and nose to give you initial impressions. ( I don't like brussells sprouts, so I can see if they are in this meal)
Photographs(good ones) can tell you things like blade to handle ratio, handle treatments, is it wide blade or a thin one?
You can spot some flaws in a good picture, like a grain flaw, or a spot what may be a crack. These can help in the formation of a constructive critique.
You can see a poorly formed or run off hamon on a Japanese style knife, or simply just a "bad" or "boring" hamon. This matters in Japanese blades, it is not opinion, it is fact. A blade with run-off hamon, poorly executed hamon or simply, an unattractive hamon is the least desired of a given group.
I would always say that one MUST handle a knife to FULLY critique it. I would also say that as you get to know the characteristics of a knifemaker's work, that there are reasonable expectations that you can develop and this helps add to your ability to critique what you are seeing, when looking at photographs.
Jerry, "coon fingering" just sounds dirty to me, and I can't bring myself to say it without laughing

. I get your point, and were I in your position, I would gave the same opinion, that pictures are not very useful in a critique.
For me, pictures tell me if I am interested in buying the knife. So do a wide host of other inputs (meeting the makers, being referred to them by a mutual friend, handling the work....).
I would say that I have made my initial purchasing decisions from a picture about 50% percent of the time. That is roughly 150 custom knives in 20 years. I was disappointed, very disappointed, twice, which would make this like a 1%-2% rate of dissatisfaction with what I have purchased, product, not process.
From a business perspective, that is an excellent rate of satisfaction, even though you want to keep it above 99%, best case scenario
I have been blessed with "a good eye", but excluding that, it seems to me that pictures are a very strong element of critique to be formed. They are not the be all/end all, but they are an excellent tool.
Thanks everyone for joining in. It helps me a lot, and I think it ultimately helps all of us.
