I have had a moral dilemma picking between these two blades! I like the looks of both, and I think I will be happy with either one, so I am wondering about other peoples experience with these knives. Any problems with either? I will be using the one I pick mostly as a dress knife, and I live in a dry place so I don't think that I will have much trouble with the M4 rusting. Unfortunately I can only get one of the two. Thankyou for your input!
