Teaching the Little Ones how to handle knives

We've been working with C on knife skills for a while now, starting with play knives and easy-to-cut things like bananas and softened butter (who knew it could be so fun to cut butter?), and moving on to a table knife and more complicated things to cut, like her own food at the table, pasta for her little sisters, spinach leaves (which I chop and add to tuna wraps, pasta, etc - all three will devour it when it's cut, and refuse it completely if it's not), softened carrots, and other fruit.  Like all "help" in the kitchen, I've found that the #1 most important thing is patience, or perhaps deep breathing, or maybe a dog to clean up quicker than the littlest ones can make an even bigger mess, or, well, all of the above.  Does it say something about me that safety isn't #1?  Probably.  But I do think about it, I swear.

The primary safety challenge is getting C to keep her little fingers away from the cutting board while mommy is chopping things.  I'm obsessive about my knives being sharp (just ask my mom, who is so terrified of my regular knives that she refuses to use anything other than my paring knife, no matter what she's chopping) and I've nearly taken my own finger off with my trusty santoku, so it's just a bit dangerous for C, and her ability to remember that I told her not to do something for about, oh, 10 seconds, to be near the cutting board.  Sure, she's aware of "sharp" and "we don't touch sharp things" and even will point out the sharp things in her books (horns, farm machines, teeth, ice-skates) but it doesn't seem to translate when there is so much good stuff to grab on a cutting board.  Despite this, I'm thinking seriously of moving on to sharp knives with her, and today at  "Simple Bites" they posted an article about Knife Skills for Toddlers,which has four simple rules:

• No Hands on the Cutting Board
• Do Not Take the Knives out of the Knife Block
• Use Two Hands When Cutting
• Keep the Knife on the Cutting Board

I like these - simple, straightforward, and (particularly the last two) encouraging safety and proper technique at the same time.   Do you have any tips to share?
