One of the most crucial kitchen tools when you want to prepare wholesome meals is a great knife. Some of my favorite and best kitchen related wedding gifts were unexpecteds (aka stuff I didn't register for), and my awesome 5" Santoku knife tops the list!
Notice how my knife flows from blade to handle- the steel is indented in the handle so that the silicon (for grip... an all steel knife, in my opinion, would sleep too easily when hands are wet from handling veggies, what with the rinsing and natural excretions from the food being cut) makes for a smooth flow overall.
My knife is over two years old and still works as great as it did when it was brand new! These tips definitely work. As an aside, I follow these same guidelines for my paring knife, though I've never had to sharpen it yet because I use it so rarely!
I hope these tips are useful in your kitchen!
