Writing as a European, I have to say that if a knife has 'issues' or serious quality disappointments then sending it back to the USA is expensive, time consuming and possibly futile... With this in mind, I think about the dozens of knives I've bought over the years from America.
Buck, CASE, Canal St. Queen/Schatt, GEC have all given me a great deal of satisfaction. Fixed blades from Bark River and Hess Knifeworks- the latter has been excellent, the former really rather disappointing in durability- not cheap in price though!
However, I've never had a knife from GEC that has had any serious F&F issues, certainly some have disappointed as I didn't care for the pattern or execution, but I've never had one that I thought I have to return. Certainly, I've had fine knives from the other companies (particularly Queen's D2 range from the early years of this century) but I've had a few unpleasant examples from all the others, yet to have one from GEC though. Now, I'm by nature intensely suspicious of group-think or fanboyism, so when I hear the praise for GEC I instinctively bridle, but in my case at least I can say the QC is very well monitored and they do not appear to send out unsatisfactory knives. On fanboyism again, there was tons of that at one time (prob still is...) about Bark River and the greatness of everything about it and the proprietor- it simply did not match my experiences though. I have criticisms about GEC, its miserly allocation of stainless knives, no sunk joints knives really, some of the patterns' proportions, drought in new frames plus refusal to re-issue certain models to keep up collector value but I cannot fault its QC programme. They are far more consistent than the other manufacturers, end.
