I chose the last option. I don't have any hard or fast rules on where to buy knives from, but as a general rule do not trust Chinese steels or heat treatments. Although I own Chinese made knives(I am not looking through 85 knives, but I am sure that I do), I do NOT own any Chinese branded knives because they have been known to steal designs and I do not support that.
If it's a Spyderco knife, I rely on Spyderco to be my feet on the ground and watch the entire process from design, steel sourcing, heat treatment and manufacturing. I'd prefer the steel to come from the USA or EU as I do not buy alphabet soup steels. I also prefer USA made goods. Spyderco I trust completely, they are one of the best knife manufacturers globally. China I do not trust whatsoever.
