One thing must be remembered. One person's experience with a brand will never represent it's Quality Control issue. However, if many gone through their experience and compare notes, the aggregated result will represent something more meanigful. This is why our forum serves as aggregator of people's experience, and thread like this is useful
Now, if a foreign (to US folks) company can have an aggregate that rates higher than a US company and offer the product at much lower price, does it say something?
Customer Service is there to take care of the issue, but there is a maximum limit where fixing defect will cost more than doing it right every time (read: almost right). No one is perfect, but blade rubbing liner or pivot that got losen up (no loctite?) is not meeting the standard commanded by the price level (50$ and up I guess). Returning product for warranty works means time & cost to both buyer & manufacturer, including 'hidden cost' which is the time & satisfaction of enjoying the knife.
Now on another thread, a foreign company in China as an example (from the numbers of buyer vs the lemon reported), is able to churn out many knives with more consistency (Do the always, centered? No. Do they rub the liners? No. Do they come sharp for slicing copier paper? Mostly. Do they come dull that it won't cut even the fold of paper? No. Are the screws loctited? Yes) than a US company, then it says the US company might not be taking QC issue serious enough, or simply gets complacent.
Statistically speaking, there is median, mean/average and standard deviation ... Excusing BM being a 'production company' and having lemon to such rate doesn't hold water, IMHO. Victorinox also produces 100,000 knives a day, but I have not seen any other production company have such tight tolerance level at same price range.
Please note that I don't hate BM. I used to have BM balisongs and keep watching BM for their Balisong lines.
The fact that such a thread not only exists, but runs 3 pages (up to now) says that BM has issue, but people are still paying attention, and not writing it off yet.
This thread, if anything, should serve as wake up call.
As someone mentioned, the market will decide the course.
