Kevin,
I too am talking about custom knives, I have never bought a knife at a flea market so I will defer to your superior knowledge of that sector of the market.

.....It's a Joke...Im laughing as I write this.....see the big SMILE
Les, you would be surprised at how many of my knives came from flea markets. 
Actually, when my wife and I travel say to Daytona Bike week, she has to go to the BIG flea market. If ever there go to the knives.
Kevin, you brought up after market price. I addressed that, I am refereing to the makers retail price. The after market can be very fickle, so that at best is a snapshot of the market at that time.
And perhaps that's where much of the 10%-15% difference of opinion we have is coming from. As I think "makers retail" is irrelevant and actual price paid is all that matters in the context of this discussion. So perhaps we are both right from the different angles we are approaching the issue.
Kevin, you are a collector of a very small section of the custom knife market...the forged blade. Within that your sub-set is even smaller (amount of makers) and then you get to the sub-set of that sub set (type of knife) and you are an elite collector within those sub-sets of the very small section of the custom knives that make up the forged market.
But Les please, even though my collection is focused there you know I follow and research a much broader market of custom knives. I would be surprised if you are insinuating that all I know is in my small collection focus.
I buy and resell custom knives, across all sectors of the custom knife market. It is my job...it is what I do all day every day. When I attend a show, I try to look at every knife. When I am at home I look at knives on the Internet. I watch the sale forums, to get a glimpse of what the after market is doing. But the absolute best information I get daily is from collectors. They tell me what they like, what they don't like, whose knives are hot, whose aren't, etc.
As I have stated several times here, I'm not questioning your knowledge or expertise of the market.
For the very high end forged blade market I value your opinion. As I know you do your homework for that market.
I can tell you with reasonable accuracy what the price range is for a particular market. This helps in determining what a makers position in that market will be. There will always be some makers who go above that price range, this is done for two reasons:
1) They are trying to get more money for their knives..."Don't Ask, You Don't Get".
2) They don't know how to price their knives for what they are at that particular time.
Imagine how many more knives would be sold if the maker actually knew how to price their knives with regards to their position in the market. Even Super Stars at what some consider a "Prestigious" show don't sell out.
All that said, I will still stick with my 90% number, even though I know it is merely an educated guess.
Kevin, question for you. With all the talk of a coming recession (albeit a short one) What affect to you think this actual or perceived recession will have on the sale of $1,000 plus knives?
I don't think you will agree here, but I believe it will have a negative effect as even though higher end collectors will still obviously be able to afford the higher end pieces, when they see a recession lower the value of their traditional investment portfolios (stocks/funds) their buying trends are affected.
Interesting though, I have found that collectible cars tend to advance in these down-turns as investors remove funds form more volatile investments such as stock and funds to invest in more tangible non-volatile items.
