This knife has a very interesting profile.  The blade starts out with a typical straight blade, which curves slightly in the front.  This is a huge benefit because it allows you the ability to use a rocking motion when cutting as well as a traditional Japanese chopping motion.
I use this knife instead of a traditional Chef's knife because it is lighter, sharper and more versatile. The hollow edges prevent food from sticking which makes prep work much quicker.
I can't say enough about this knife.  I like it so much that I've decided to purchase the smaller version of it for my daughter.
