I purchased a Queen City Large Sunfish from GPknifes. I like the knife other than the fact that it is extremely hard to open. I own a dozen other good quality knives and none of them are even close to as difficult to open as this. I called the people at GP and the lady answering the phone said it will loosen up with use. I have spent hours working it with a glove and it ain't gettin any looser. I called Queen Queen City Knives for help and their warranty dept never picks up. I have left several messages and no one has returned the call. My question is: Is their something I can do to free up the mechanism? Thanks!
