I currently have a chef knife, nakiri, paring, and a santoku. I'm looking to add some knives to have a more complete set. I'm thinking about a 9-10 chefs knife, petty or 7 inch chef knife, honesuki, and a suji. Any other suggestions? Also, what do you think I would use more and be more versatile, the petty or 7 inch chef knife? Keep in mind I work in a professional kitchen and will probably be using them on a daily basis.
