This block have every knife you would ever need in a kitchen.  The Pro line is one of the top of line Zwilling products made.  the knives are made from German Special Formula Steel and forged from one piece of steel.  This makes for flexible, yet durable knives.  They have also been ice hardened so blade edges stay sharper longer.  Each knife has a curved bolster (middle of the knife) that encourages you to hold the knife in a pinch in the correct pinch grip.  No short cuts are taken when making the steak knives, they are made the same ways as the other knives.  Really a life time set - and that's exactly what the warranty is, lifetime.
