Important question - Do you want to do monthly knife SHARPENING using a grinder/whetstone? (A honing steel is not a sharpener) If you're all right with that, you really cannot go wrong with carbon steel Japanese knives or French sabatiers. I'm kitted out with them and they're lighter, exponentially sharper, and cut much easier as a whole. If you want something heavier and lower maintenance, go with the German knives.
Regardless of your choice, you really need three knives:
1. An 8-10" chef's knife or gyuto,
2. A 2.5-4" paring/petty knife, and
3. A 10-12" serrated bread knife
Anything after that is just icing on the cake.
In addition, the best think you can buy for your knives is thick, good quality maple cutting board. Boos and Michigan Maple are always safe bets. Just make sure to keep it oiled so it doesn't split, and NEVER run it through the dishwasher.
