Hi congrats on getting hitched. Avoid purchasing a set as most contain knives that are either redundant or not useful. Go with a chefs knife, a paring or petty, a serrated bread knife, and meat slicer.
The bread knife and meat slicer are likely to be the most used occasional usage knives. For a bread knife (10+); the reversed scalloped edges (MAC Superior, Shun, Wüsthof Super Slicer) work better than a typical serrated edge (particular on hard, crusted artisan breads), but any decent (~$20) serrated knife will work and just create a few extra crumbs. For a meat slicer; Longer (12+), narrower, stiffer blades are better. Go with either a Carving knife == curved tip for ceremonial tableside work or Slicing knife == straight tip for cutting board.
The Paring (3-) or Petite (15cm) when you need something less cumbersome, more precise than a larger chefs knife. I find a petty more useful than a paring knife, but most choose a paring knife. Paring knives normally arent used against a cutting board or for difficult items, so a high quality blade is not needed. The better ones usually have thicker, harder blades that dont follow contours well. Shun and Mac have excellent petties and paring knives. The Forschner and Kuhn Rikon paring knives (<$10) have stupid good finely grained, thin, flexible blades.
The Chefs knife will likely be your main workhorse. Most males opt for a 8 or 10, and women like a 6 or 8. I would suggest avoiding going below mid-high level European knives (they suck) and above entry level Japanese knives. Theyre great, but require committing to learning how to use and maintain one properly. The Forschner rosewood, Tojiro, and MAC are excellent.
