The 5 Best Soap Cutters

When you make soap, you need a soap cutter to turn your soap loaves into bars of soap. In addition to cutting the soap, soap cutters play a large role in the appearance of the bar. When you cut a bar of soap with a wavy blade, it's going to look different than if you use a straight blade soap cutter. These will both look different than using a wire to cut it. So, think about how you want your soap to look, and let that decision guide you into making a purchase. No matter what type of edge you're going for, here are five of the best soap cutters on the market. Each of these will easily glide through your soap, helping you create uniform bars without a lot of hassle.

Frequently Asked Questions

How do you cut soap?

When you first make your soap, it’ll be in one large loaf shape. You must cut it into bars when you’re ready. To cut soap, you need a soap cutter, a knife, or another blade. Then, you gently apply pressure to the soap with the blade. It will glide through and leave a bar. Then you keep cutting, until you’ve reached the end of the loaf and turned it all into bars. You can cut free hand, use a soap cutter loaf mold, or use a ruler to measure where you need to cut.

Should I use a wavy blade or a straight blade to cut my soap?

When you use a wavy blade to cut soap, the sides that you cut will have a wavy design on them. When you use a straight blade to cut a bar of soap, the bar will have straight sides all the way around. There is no right answer to which style of soap cutter you should use. It is really based on personal preference, and how you want the bar of soap to look in the end.

How do I clean my soap cutters?

When you’re done cutting your soap loaf, you will want to clean your soap cutters before storing them. Follow the directions for your particular blade, to ensure you wash them properly. If your blade has any wood on it, make sure you wash it by hand and don’t put it in the dishwasher. Typically, you will use warm soapy water to clean the cutter.
