Congratulations on your place in line. Wish I had another one on order.
As to your question, knife designs do tend to be trendy things don't they?
Personally I buy knives that I like, not as "investments". If it's an investment your seeking, your $400 may better serve you in a more traditional type of investment strategy. But there again, as Ernie only required a $25 deposit (and not even that in later years), you could still have done that and pocketed the interest to boot.
If I were you, I'd keep my place in line. It's not costing you anything to wait.
Tastes do change over time. If when you get that call that your knife is done, you could pass on it or you could be a real stand up guy and pass your newly finished, unwanted knife to someone else. I did just such a thing recently.
Two years ago I had ordered a knife from a custom maker. By the time the knife was done, I had lost some interest in it, but knew that someone would love to buy a beautiful, collectable knife at the makers "retail", but didn't have the fore thought to get in line years ago.
I told the maker I would call them back the next day to make the shipping arrangements and emailed a few folks. A buyer was found in under an hour.
Everyone was happy. The maker got paid for his work and a collector got a piece for their collection that they were not counting on (isn't that the sweetest way to get a knife).
Personally, I didn't make a dime on the deal, just helped some folks out and still fulfilled my part of the order.
Just my thoughts on the subject.
