Well balanced, mid-sized and a comfortable weight - the santoku is a superb choice for the cook who's looking for one knife to do many jobs.
The Santoku blade shape will be new to a lot of Westerners but once you've used it you'll see that it make a lot of sense. Santoku literally translates to "3 uses" (slicing, dicing and mincing) which makes it a perfect all round choice and an essential in any kitchen.
