Finally a knife I really enjoy working with!  This 5.5" Santuko has replaced my 8" chef's knife almost entirely.  Love the shorter blade, lighter weight, and sharper angle.  The hollow edges are great for reducing air pockets which is why my foods no longer stick on to the blade. 
The Zwilling special formula steel, doesn't rust, holds an edge and is easy to re sharpen.  Also dishwasher safe which is a bonus in my home.  No longer dread working in the kitchen.
