We recommend that you cut your soap with a mitre box and putty knife. You can watch Emery demonstrate how it is done in this video:
It is possible to cut soap with a kitchen knife, but we don't recommend it as the knife can slip.
If you order a soap log or bar of soap that you intend to cut, please cut it as soon as you receive it. The longer soap cures, the more difficult it is to cut.
We have soap in several different sizes (see goat milk soap size comparison chart) and do not offer custom cutting into smaller sizes. Thanks for understanding!
