Hi, I'm trying to decide between the Ontario Knives RAT 5 or RAT 7. Is there anything that would be A LOT easier with the RAT 7 that I could not do with the RAT 5? I'm leaning toward the 5 because it is 2007, and I don't feel comfortable walking around with a 12" knife on my side - the rat 5 will draw enough attention. But if the rat 7 is by far a better all around survival/camping knife, then I would go with that. What are your thoughts?
