This block set has it all.  Did my homework before I purchased this block set.  High carbon, German steel is the best way to go.  The blades stay sharp, and hold an edge.  When I do need to sharpen I no longer have to run out to get them sharpened professionally.  The slots in the block are designed to sharpen the blades, by just running the blade a few time through the slot.
The assortment is compatible with all the jobs I preform in the kitchen.  I love the molded handles, which are so comfortable, and lighter than the riveted handles. I also find that the handles are less prone to holding on to bacteria because of the one piece design.
These knives have a lifetime guarantee, which is piece of mind for me.  I can also toss them in the dishwasher without a worry.  The Four Star line also has a large variety of other cutlery pieces, so I can definitely add more matching knives.
