While it is usually a simple fix, there are knives that nothing works-the blade is bent.
The thing that gets to me is that we are willing to "fix" brand new knives!! It is not just Benchmade, either.
Let them know that they screwed the pooch again! Make them fix it and pay shipping both ways- it is their fault. Personally, I would contact the seller and send it back to them.
They will continue sending out inferior knives without motivation to make them right in the first place. The only thing that companies understand is MONEY. Cost them MONEY!
