Well,
Guess I should be involved in this thread. I wish I knew the all the truth and nothing but the truth. But, I am not all knowing........
First off, I will state from personal experience, reading and hearing - that the fit of SAKs are second to none and I mean NO other non-custom maker on planet earth.
As a collector I handle knives of past years more than I do current models. To be honest I have only bought a few limited edition 300 series knives in the last 5 or 6 years. All those have acceptable fit and finish on my inspection. That acceptable level is NOT the mountain top SAK level but a nice tight Case like fit. I would recommend that if you were to buy a new 300 series knife, I would do so in person so fit and finish can be inspected BEFORE purchase, I would do that be it SAK, Case or Buck. My new Bucks have always come sharp, not as sharp as I can make them but sharp for everyone else but Forumites.
I would hazard an attempted un-biased opinion, like I say I am a collector mainly of 70s and 80s Buck 300s, but my opinion is that why would a company with lifetime warranty have a quality control level that had customers sending back wiggly bladed knives ? What I have heard from several and various knife company people is that warranty work is the least cost effective work in their shop.
Building your manufacturing process for a planned percentage of failure is standard engineering planning, all companies have an idea what theirs will be.
If Buck is letting a lower quality increase in the percentage of that engineering plan then I will be getting off their boat.
What I am hoping for is that there is a silent majority effect, that there are a lot of purchasers of non-wiggly Bucks that are silent.
Fit and finish of Buck imported knives has been a hotly debated topic. Most often they receive glowing reviews from users. I have two imported two blade trappers, finish and fit are equal to any Case. I just want them to say USA...........I am a cold war child.
They are imported so the individual knife can meet the price point requirements of a hugh seller of Buck knives.
A person should not have to send back crappy brand new knives.
But, Buck will make it right in the end if you got one, but Yes, you shouldn't have to go to the expense and trouble..
I have a goodly number of really solid 300 slipjoints, most are old, most were made by Camillus, some after 85 made by Buck. My new limited edition Bucks are all solid. I have no experience with the new changed models. I never buy the first year when cars change design....
I would and will not accept anything less than a Buck to function equal to a Case. I hope that will occur or I am really gonna be miffed.
