As I recall from the TV commercial, the point of the brick thing was that you could saw the knife against the brick for numerous strokes without dulling the knife. I don't remember them saying that you could cut a brick in half using the knife.

The coffee cup wouldnt be cut in half if the cup was able to sharpen the knife.
I believe the knife can "cut" a brick in half because the hardness of the brick is less than the hardness of the knife, and because the knifes tiny serrations act as grinders, rather than cutters. So when you cut that brick, you were actually very slowly grinding through it, ie, making small scratches in the same places over and over, scratching away the brick material.

Awesome! I am a blades gal and I have a Henkels and Wusthof kitchen set that I usually have sent out to be sharpened. Since times are kind of hard I havent done it in a while and have been quietly going mad dancing between knives as they grow ever duller. I actually have a 7 and a 9 inch Santoku and I can't wait to try this.

I personally like my Ginsu knives for cooking. Remains one of the only As Seen On TV items my wife ever got, that actually seems to live up to the claims. The other is the Foreman Grill, man I love that thing....and the Magic Bullet (a must have at parties).
Of course, there's plenty of other crap she's bought that just collects dust....lol.

I've started using this in the kitchen just to keep me from having to unpack my ALICE pack to find my knife sharpener. And you never know. Finding a broken mug in the woods can be like finding gold now! lol

Ceramic coffee mugs will work... on 440 stainless steel or softer... sorta...eventually, with alot of work, and hope that you dont make any mistakes.
It's not for the layman... you can get a better edge with a $2 china-made kitchen stone..or a $5 ceramic rod sharpener, with 1/10 the effort and less chance of ruining the bevel.
Odds are.. you'll ruin the knife with the mug before you get any useable results.
For example: The edge on my blades cannot be reproduced with a coffee mug.
You cannot maintain a correct bevel angle with a coffee mug.
Unless you are a seasoned knife sharpener, please don't destroy your nice blades with this method.
Knife sharpeners cost so little to begin with, there's no excuse not to own at least one.
lastly, you will most likely ruin your edge with this method.
it will work in a desparate, last resort situation, but if this is all you have to sharpen your blade in a SHTF situation, you are not prepared and have bigger problems already.
a few more posts and I'll start posting tutorials on knife making and sharpening.. then you can all see the downside to many of these types of tricks.

I found this on youtube and thought it was a neat piece of info to have. Not only is it good for the chefs that end up invited to Thanksgiving dinner and find themselves being the "chef of honor" in a dilapidated kitchen with dull knives, but you never know what you'll have at your disposal in a survival situation. I'm cross posting everywhere to get the info out.
