It is that Bose fever that is partly responsible for the secondary market prices being high!!! People want them bad and make offers that you can't refuse.
It happened to me with my first Tony Bose knife.. At the time, I was sitting behind my table in California a number of years back and a collector from Canada, whom I didn't know at that time, came and saw my little gents in pearl. He wanted it so bad that he made me a very, very high offer. As a dealer that does this full time for a living, it was almost impossible to say no. I sold it and have regretted it ever since. Bose fever is the name for it... I get it myself. But, I am not as "well to do" as many collectors are. I can't pay those prices either for myself. I also have alot of trouble parting with Bose knives. Sounds silly coming from a dealer. But, it is true.
It all comes down to supply and demand. And if the demand is great, the supply is limited, the price is going to increase.
