Cake Knife by Marsh Custom Knives.  "People often ask why it’s called the cakeknife. Well it got it’s name for the simple fact that it was the knife we cut our wedding cake with. Why cut the cake with the provided piece of imported sterling silver when we could do it with a handmade folding knife? So that’s what we did."  After reading his description of this knife I now want it just because he had the Kohonas big enough to use it for such purposes.
