I don't see why I would expect less in regards to customer service from Cold Steel than someone else, this certainly wasn't the case when I had a problem with a Becker, which is one of the reasons I would recommend them readily over Cold Steel, far greater customer service. I have also seen similar issues with QC with Becker, however all were promptly dealt with. Becker also doesn't promote the hype that Cold Steel does, with testing that no one can verify without voiding the warrenty on their knives. So when it comes down to similar models, Becker wins easily. Of course Cold steel has a *lot* more models, a lot of which there is no similar Becker blade.
Yes I have also heard various rumors about the steel and the manufacturing connection between CS and Becker, I heard them when Becker was launched several years ago, and that is all they are unless you actually get someone from either company to make such a statement, and thus it deserves no public attention as do any rumor.
This again is of course nothing more than a side issue, of the original point which is that Carbon V isn't a specific steel, but a brand name - read the archives. Yes, it can be a very solid tool steel, and yes lots of people therefore are well pleased with it, I have had very nice "Carbon V" blades.
The argument is interesting though, first I am "biased" because I have a problem, then its because I am consistent in such a perspective, now I am not an ordinary customer and should therefore expect less customer service as normal. The latter point is even inherently weak because at the time I had the problems with Cold Steel I had just done a handful of reviews, this was years ago. Plus I have no problems even now with customer service issues with other blades. I recently had a problem with a blade with another production company (review will be up in a few weeks), fired off an email to the manufacturer, got a reply in under a day.
