Hey everyone, my boyfriend reminded me last night that I hadn't given you the best cake making tip in my arsenal yet.
If you need to carve or level a cake, instead of using a knife, go to your local hardware store and, for a few dollars, purchase a hack-saw blade. They are long (most about 12") and very thin which makes them great for leveling. Also, they hold their perfect straightness when needed, but can also be coaxed into perfect curves for domes. Also, the best part is, once you use them for a curve, they bounce right back to perfect straightness.
They do have very fine teeth, which make for the preciseness, but you must make sure to work slowly back and forth in a sawing motion when using to avoid tearing.
Hope this lends a hand to someone!!
