Agree with the previous two comments, for home cooking a good 18-20CM chefs knife is far superior to a load of duff knives!
even if you think you need more, realistic you need a bread knife a paring or utility knife and a chefs knife anything more is just icing on the cake!
regarding chef knives you could go western or japanese, japanese is also called a gyuto and tends to be thinner in blade and width, but is not quite good at the rocking motion a western knife brings but tends to stay sharper for longer as they use a very hard metal for the knife core and dont get wedged so easily, just pop into a local department store to get an idea of the knife feel, this is very important.
Western= Henckels and wustorf
Japanese= Global and Shun
Sabatier is just a name not a knife brand like the above, anyone can add sabatier to their knife its not a trademark but a manufacturing process, so if you see a cheap sabatier, it is just that, a cheap crap knife.
I.e Many people recommend global, they are OK knives, however i just cant get on with its handle, prefering the pakkawood handle of my knife, so its "feel" sold me.
