I just got a Boker 5464 Congress, and am just wondering what the reasoning is on this knife having two identical sheepsfoot blades. Reasons I can think of: one sheepsfoot for food, the other for utility, or maybe one is a "backup" in case other goes dull. I've seen another Congress model (Queen) that has two sheepsfoots and two pen blades. Any thoughts on repeated blades or history of the Congress design would be much appreciated. Sorry if this is a really stupid question.
