Where can I get a cutter and

fter doign a bunch of reading I figure d out that tryign to make soap would be dangerous for my health and maybe the folks that would buy the product. A very technical craft. So, I did the next best thing. I bought like fiv epound logs of soap from a soap maker. Now the problem is I can't figure out what or how to cut them up into slices without makign a giant mess.

I would be so greatful for any help or advice that you soap crafters may have. Thanks! : )
