The Bladeforums Knife is quite unique because of the build up, the Forum input of the outcome of the Knife combined with the limited number of the Knife etc.
I think if I were you, I would go on the Trade forum asking for a trade on the Knife you want, it is totally your business what you and that buyer wants to shell out for the knives concerned- no else's concern at all, It doesn't matter what you do, people - because they missed out will jump up and down and have a hissy.
What people may ask is why are you using this Knife to Trade when you may have others? - is that what you bought it for for more bargaining power ? may not be so, but will be thought, in the end, its all down to you, you own it, no one else does.
I own MANY knives I have had to pay double and more to get - its how it goes, the buyers will set the level of the market in how much they want a particular model.
If I for some reason need to sell my knives at any time, they will go at the going price, and I am not a flipper.
A flipper is someone who joins the queue and gets a knife, knowing there's a screaming shortage, then sells soon after receiving the Knife for profit.
I would like to think that the Knives I buy - if I sell later will make a profit, That is not flipping in any way, if you disagree think about it when you sell your house or classic car - are you going to sell it for the same price you purchased it for? no, and no one else would, sure there's a difference in investment values here ( in some cases ones knife collection stands at tens of thousands ), but the exact same principle.
If a Knife doubles in value or triples in value in the 5 to 10 or whatever years I own it, then I get a little back to counter the amount of money I have lost with this passion of collecting Knives.
