i would not buy a Chinese made buck. not that buck is the very best quality at all, but because generally when you out source to China, its to save costs and profit.
if WE knives was making them, it would be a different story, id buy that in a heart beat, as they have proven quality (same with only a few others like Reate).
id probably even buy one if it were made in Taiwan if the quality was there (for example spyderco Taiwan factory).
but if it a buck was stamped china, i wouldnt touch it unless i knew it was a quality product.
The other thing is... would it have the BOS heat treat? if not, no way hoe say
with all that said, i dont think Buck is anywhere near the best quality, and they dont provide high end steel types, but some of the steel they do have is often optimized by the BOS HT, which is better than the budget steel from china.
