What do you all use to sharpen the dowels you put through the entire cake? I usually just use a 1/4in dowel and can use a pencil sharpener, but what about larger dowels? In Edna's video it looks like she's using a 1/2in dowel. How on earth do you sharpen that?

I am pretty sure you can buy a larger manual pencil sharpener. When I need a dowel sharpened, I use a box cutter and whittle the end into a point. I don't use dowels, except in a 2 tier cake or maybe a sculpted cake. I use an SPS system for all wedding cakes over 2 tiers high.
