Unless the three tined fork has the outside tines spread out an an angle (which would be a sea food fork), the only difference between three tine and four tined forks is style.
You'll find both salad and main course sized forks in each "set," and both will have either three or four tines.
When in doubt at fancy dinners, use the "outside to inside" rule. Use the utensils at the extreme left and extreme right with your first course and work your way in with each succeeding course.
You finish with the dessert utensil(s) at the top of your place setting. |
