Hey all, I'm looking to buy a knife. Preferably a Chef's knife. I'd like one that I don't need to sharpen very often. I really like the hammered look and right now, I'm looking at Shun's Premier Chef's knife. I think they have them from 7" and up to 10". What do you think of the Shun Premier series? would you suggest a different one? And what size would you suggest?
