I believe if my memory serves, that SK-5 is a Japanese steel. Since Taiwan does not have their own steel industry, it was probably a move to improve manufacturing consistency. That means labor costs go up, hence the increase in price. Basically, my understanding is this, that Taiwan allows a knife manufacturer to outsource manufacturing while controlling the use of a particular type of steel (see Benchmade's use of 440c, N690, etc in their Taiwan offerings, Spyderco's use of S30V, Cold Steel with 1055, others.) Now, if you chose to source your steel and your manufacturing in China, you get a certain price point ala the Byrd Line, Tenacious, Benchmade Pika II, VEX. You could source your manufacturing in China, with steel from elsewhere, ala Cold Steel, Boker with SK-5, 1055. Or you could source steel and manufacturing to Japan, and you get the pricepoint of the majority of Seki made blades of Spyderco, AG Russell, KAI, etc. My impression from research and buying is this, Japan and the United States and Germany to some extent, you are going to pay top dollar for steel and manufacturing. People are willing to pay. If you want to save money it's either Taiwan or China, with benefits to doing it several ways. I think Taiwan has an excellent reputation for Manufacturing and since the steel can be sourced from Japan or the US relatively easily, its a good way to control manufacturing.
