I have the following two knives. A Case 62087 and a Remington. Both are reffered to as "premium jacks". But what does that mean? Are they called premium because of the serpentine frame, like sotckmen are called premium stock knives as oposed to cattle knives? Is any serpentine jack a premium jack? Texas jacks are on a serpentine frame as well but Texas reffers to the square bolsters, right?
So please tell what you understand to be a premium jack and don't forget the photos!
