If you invest in the agbay, you'll wonder what you ever did without it. I use mine on every cake and it cuts though everything like butter. I have the one blade model, but the two blade is really cool, but i really couldn't justify the expense of the extra blade, as i can just not be lazy and adjust the one bladed one to do the job. Its easy to use and very sharp (watch your fingers)
No i don't own the company, just a happy customer.
