Years ago I bought a bud haffner wooden soap cutter which is fabulous. He now makes metal ones. Find him on Etsy. I would recommend anything he makes. You can choose any width for your soap bars mine are 1 1/4 inch as they shrink in curing and I find 1 inch too thin.

Buy the widest cutter you can afford for ease of use. Use any length mold you want. When you get a cutter work out a piece of timber or something the right height to sit a soap longer than the cutter on. If you’re making a lot of soap 18 inch molds are great. But nurture silicone ones are the best.
A cutter will last you forever don’t stint on it.
