Please explain Case/Bose collaborations. I'm seeing Case/Bose knives priced all over the place. Some of the Case/Bose knives have the Case emblem, these are usually the lower priced ones, other Case/Bose knives have a different emblem (dogbone?) and they are usually higher. Am I seeing things? Is a Case/Bose always a Case/Bose and the price differences are because of steel or something else? Thanks.
