Hi HVR,
The world is shrinking, and constantly changing. The "big picture" view cannot be ignored.
As technoogy and material knowledge is moved all over the globe, everyone from China and India to jihadists have access to the latest materials and technology.
As money markets change in connection with that technology and materials knowledge, there seems to be a lag in valuation. Whether it's the Japanese Yen going from 350 to 105 (15 years) or the Euro going from 80 to 125 (4 years), some country at any given time is going to have a pricing advantage, for a while. Right now it's China.
Business will always try to take advantage of that "lag" in the currency values. Or may be be required to follow others into that country in order to be competetive. There are many markets where China has already taken the market.
I can't speak for any other companies, but Spyderco is making knives in a number of different countries, (USA, Japan, Taiwan, Italy and China [byrd])but we design the product, control the quality of manufacture and the materials.
Our "byrd" brand is a low cost alternative to our Spyderco models. Because of the dollar / Yuan difference, the value is difficult to beat. I see many other major brand have been manufacturing in China far longer.
hope that helps.
