The Miyabi Santoku comes in two sizes, 7 and 5 inches. My preference is the 7, but I have many family members who prefer the 5. Either way, this is a terrific chopping knife. 

The width of a santoku, from tip to heel make it extremely stable to chop thick foods - a large roast, a butternut squash, an eggplant. The sharpness of the Kaizen also makes it easy to make elegant thin slices too. The hollow divots (called a Granton edge) reduce friction and allow food to slip away easily. 

Adding to the enjoyment of this exceptional cutting tool is its beauty. The Damascus-style polishing showing the layers and the linen Micarta handle with finishing details combine to make using and owning this knife a joy.  Hone regularly. Hand wash. This knife will be sharp and beautiful for a lifetime.
