I have several Vantages, and I've given some as gifts.
I have a daily user (Avid) that isn't perfectly centered, but opens sure and certain, locks up well, and cuts like the dickens.
I have a couple of PaperStone handled Select models. They both have handle blems (sold as blemished), but the blades are solid, centered, and smooth.
I have another Avid that's centered and solid.
I have returned a single Vantage, a small Select, because it was too hard for my arthritic fingers to open easily. I traded up from the small to a large -- an excellent copy -- and gave that to my son.
I have an unfair advantage, I suppose, because I've never had to order one by mail. I've either gotten to pick one from stock in a store or at the retail counter at Buck's factory. It's easy to pick the perfect ones when you have several in front of you.
However, mail order or not, if you don't like the way it is when it gets to you, Buck will make it right.
