The Four Star line of Zwilling knives celebrated it's 40th anniversary a few years ago.  At that time I was able to purchase a 7" Chef's knife at a fabulous price, so I decided to give the line a chance.  
Finally had an opportunity to purchase a block set and decided on this one.   I already knew how much I liked my Four Star 7 inch knife.  Zwilling special formula steel is sharp, and durable.  The molded handle is extremely hygienic, and is also dishwasher safe.  Zwilling is a leading global cutlery company, offering customer support if needed.
Purchasing this set gives me the assortment I was looking for, at a price much more economical then if the pieces were purchased by themselves.
