The Pro S is a traditional German knife line.  It is fully forged, has a full tang, and the three rivets on the handle which give it a nice classic look.  Love the assortment because it also includes a small Santuko which I use as a chef's knife while cooking with my partner.
The block also has additional slots which allows me a location for some of the other knives I already have.
Zwilling is a top manufacturer of German high carbon steel cutlery and has been in business for over 280 years.  I know my money is well spent, especially with the life time warranty that guarantees the performance of these knives.  Also dishwasher safe which is a must with our busy schedules.
