ChompSaw | The Original Kid-Safe Power Tool for Cutting Cardboard | STEM + STEAM Educational Toy for Boys and Girls Ages 5+

Designed for Young Makers & Creative Play: Empower kids to bring their ideas to life while encouraging hands-on creativity, problem-solving, and spatial reasoning.

Safe, Fun, & Easy to Use: Unlike box cutters and scissors, the ChompSaw has no sharp blades or spinning parts to keep kids safe!

Perfect for STEAM Learning: Great for DIY projects at home, classrooms, libraries, and makerspaces.

Cut with Precision: Just lift the lid to find your power supply, plug in the power cord, and start creating! The ChompSaw is ready to use right out of the box and designed to cut most materials softer and thinner than 3mm cardboard (roughly 2 pennies tall!) To guarantee our machine is safe for little fingers, the ChompSaw is limited to 3mm thick cardboard, think your average delivery box. For the best experience, score or compress thicker cardboard first and apply consistent, downward pressure while cutting.

Trusted by Parents, Teachers & STEAM Educators: The ChompSaw is more than just a toy, it’s a learning tool that helps kids develop fine motor skills, coordination, and engineering thinking. Used in STEAM programs, summer camps, and workshops, it’s an educator-approved way to teach power tool safety and inspire the next-generation of inventors.

Join a Growing Community of Makers: Chompshop was founded by graduates of the Integrated Product Design Master’s program at UPenn and its a small business dedicated to inspiring creativity. We’re here to help your makers every step of the way — visit our website for video tutorials, project patterns, and full-access to our customer support team.

Safety Certified for Peace of Mind: The ChompSaw meets rigorous safety standards, including ASTM F963, CPSC, CPSIA, and CA Prop 65 compliance for a fun and worry-free experience.

The ChompSaw runs at about 70–75 decibels, similar to the volume of a household vacuum. If your child is sensitive to noise, we recommend using ear protection. Saftey gear like earmuffs and googles (though not at all necessary) can be a fun part of the experience and help kids to feel like real builders while teaching power tool safety.

Purchase of a ChompSaw is backed by a 1-Year Warranty and hassle-free returns.

Experience the ChompSaw by Chompshop, a power tool built for kids by two UPenn product design graduates. Cardboard is everywhere and kids love building with it, but scissors cannot cut it and box cutters are too dangerous. The ChompSaw solves both. It chomps through cardboard the way a jigsaw cuts wood, just push material into the machine and start cutting. A white marking on the cutting head guides cuts and indicates width. Kids guide cardboard with both hands across the cutting mat, building confidence with every project they bring to life. Featured on Shark Tank, named a TIME Best Invention, and a Creative Toy of the Year Winner. ChompSaw is built with the classroom in mind. A few machines can support up to 30 students in a single classroom or makerspace. The ChompSaw integrates with NGSS curriculum standards, making it a fit for STEAM programs, design-thinking labs, and project-based learning. Tactile, visual, and hands-on building supports students of all abilities and learning styles. Whether students are constructing science fair models, engineering marble mazes, or prototyping catapults, they plan, test, troubleshoot, and iterate on their own. Tested with real kids, teachers, and educators before launch. Made for the parent who wants their kid building real things, not just watching screens. For the educator who believes hands-on beats worksheets. For the kid who wants to make something they actually designed. A go-to activity for rainy day projects, school break crafting, birthday party stations, after-school maker time, and holiday gift-giving.
