Victorinox 10" Roast Beef Slicer Knife, Straight Edge, Rosewood Handle, 40143. Our classic, traditional rosewood handle is designed to provide maximum comfort at all times. Renowned rosewood handles feature a carved handle design with the unique beauty of natural rosewood, extra durable. A slicer serves a similar function to a carving knife, although it is generally longer and narrower. Slicers are often more flexible and as such are better suited for slicing ham or fish.
