These are great 12” or 14" slicers for large cuts of meat like Prime Rib and Turkey. The granton edge keeps food from sticking to the knife and keeps it lighter. They come professionally sharpened and are dishwasher safe. Choose your size based on the size of chef knife you prefer to use. If you normally like an 8" chef knife, you will probably like a 12" slicer. If you prefer a 10" chef knife, you will probably like the 14" slicer. They are both the same shape - long and narrow. They are both very ergonomic and will feel very natural as you thinly slice meat.
