Yes! It doesn't matter how expensive your wedding registry knives were, they will become dull. Once you have a sharpening kit, you realize that the difference in knives doesn't really matter that much -- you just have to sharpen softer steel more often (neglecting balance and preference). Sharpening my knives is my Zen activity.

Don't ever put knives in the dishwasher. Ever. I have proof after a visiting family member put one of my very sharp knives in the dishwasher and there are three visible nicks.
