The ultimate guide to polymer clay cutters – everything you need to know

What are polymer clay cutters?

Polymer clay cutters are molds used to make precise cutouts in polymer clay. They are frequently used in jewelry making, especially for earrings. At SI Originals, all cutters are 3D-printed with a sharp 0.4 mm cutting edge for perfect detail. Most cutters are also suitable for other materials such as Fimo, ceramic clay, and cookie dough.

Types of clay cutters

There are different shapes and styles of cutters, each with their own application:

• Basic shapes : circles, squares, drops

• Flowers & leaves : ideal for natural designs

• Clusters : multiple shapes in one cutter for fast production

• Sets & combinations : perfect for matching earring components

• Custom cutters : completely custom-made

What do you look for when choosing?

• Edge sharpness : the sharper the edge, the tighter the cut.

• Material : PLA is strong and durable, perfect for clay and cookies.

• Size : Choose sizes that fit your design (e.g., studs vs. hangers)

• Type of project : jewelry, keychains, cookies or ceramics

Tips for use

• Use your cutter on a smooth, clean surface.

• Push the cutter evenly into the clay or dough without wobbling.

• Gently lift and, if necessary, use a silicone tool to loosen.

• Clean with lukewarm water and a soft brush after use.

Common mistakes

• Using clay that is too dry or too soft.

• Not pressing the cutter down properly or pressing it down crookedly.

• Don't use cornstarch with complex shapes – a little cornstarch on your clay or cutter helps prevent the clay from sticking, especially with fine details.

Extra tools to combine with

• Drill guide tool : for precisely drilling holes

• Transfer papers : for unique designs on your clay
