The prices for the daggers is growing because the new doorway to the market opened- Russia and Ex-USSR, in Germany the prices for the blank weapon was grow over a couple of years twice. The same started in USA, due of the same equivalent in USD ( 1000 USD in states-1000EUR in Europe) all european dealers buy the stuff in states to resell it in Europe. But as I know a lot of Russian dealers now visiting SOS and MAX, due of cheaper buy in States. But if the items sold quick and easy- peoples starts to think- why not to make them expencive?!
Another way- in the future the eastern market will be not too hungry and all Europe will sell it back to states ( who knows- probably the USD-EUR position will changed backward)
