I never enjoyed the task of chopping an onion.  Too many tears and it usually turned into a messy pile of unven shapes and sizes.  With a little guidance from utube and this incredibly sharp santoku, I've mastered the task.  The razor sharp edge slices through an onion or any vegetable with the greatest of ease.  The "dimples" help keep food from sticking to the blade.  
This is a slightly heavy knife, which I love, because the knife does the work for you.  Great balance and the handle fits securely in my hand, no slipping.
