Either one will be great. Magnacut is just the latest and presumably the best. My experience is that Magnacut holds an edge better than any steel I've owned. But, M390 is also excellent.

I found a few Herman folders that really caught my eye, but I'm hung up on steel. For normal outdoor use, camp chores, and everyday carry, would you go MagnaCut or M390?
