Modern Coffin Polymer Clay Cutter – Halloween Jewelry Making Tool

If the cutter is available in only one size, that size will be listed in the product description. For cutters with multiple sizes, please check the reference image included in the listing—this image shows exactly where and how the cutter is measured. The size listed reflects the actual size of the clay piece after cutting, so you can confidently choose the best fit for your project.

To keep your Rockrose Studio Supply cutters in excellent condition, hand wash them gently with warm, soapy water after each use. Avoid harsh scrubbing, abrasive tools, or high heat, which could dull the edges or affect the cutter’s shape. Store your cutters in a cool, dry place, away from direct sunlight or heat sources.

PETG is strong and durable, but applying firm, even pressure during use will give the cleanest cuts — avoid forcing the cutter through clay, as this can compromise the edges over time. These cutters are designed for polymer clay only and are not food-safe; please keep out of reach of children.

With proper care, your PETG cutters will remain reliable and precise, ready for countless creative sessions.

Our cutters are 3D printed in-house using premium PETG, a high-quality thermoplastic chosen for its durability, strength, and long-lasting performance. Unlike PLA, PETG is more challenging to print, requiring precise handling, but the results are worth it: a smoother finish, stronger edges, and a tool that stands up to repeated use without warping or cracking.

By upgrading to PETG, we ensure that every cutter is professional-grade and reliable, offering a superior experience compared to standard 3D-printed tools. This careful attention to material and craftsmanship reflects our commitment to providing tools that creators can trust.

All new cutters are printed in white, so please note that the colors shown in product images (pink, black, grey, etc.) are from previous stock and may not match the cutter you will receive. The design, quality, and attention to detail remain the same — each tool is crafted with care for your creative hands.

Thank you for supporting our handmade process — we can’t wait to see what you create with your new Rockrose Studio Supply tools.
