Think of it like a precision hole punch that runs at high speed. Within the metal safety guard, the cutting tool oscillates up and down, nibbling out tiny half-moon pieces of cardboard. The scraps are automatically collected in the dust tray!

Frequently Asked Questions
The ChompSaw was designed for cardboard (roughly 2 pennies tall) but also works with most materials thinner and softer than 3mm thick cardboard like felt, fabric, and craft foam.
However, since our usability and durability testing focused exclusively on cardboard, we can’t guarantee the ChompSaw's performance with other materials. If you experiment with harder materials, we will have replacement cutting heads available for purchase.
Important: Do not attempt to cut metal with the ChompSaw! While the cutting mechanism may resemble some sheet-metal tools, the ChompSaw’s design prioritizes cardboard safety and performance, making it unsuitable and unsafe for metallic materials.
Ages 3 to 103+!
We put the ChompSaw through all sorts of safety testing to guarantee our machine is 100% kid-friendly (it won’t cut fingers or snag on hair or clothes!) for inventors aged 3+. It doesn't matter how many candles are on your cake, building something with your own hands never gets old!
Absolutely! The ChompSaw has been independently tested against standards for children ages 3+ in the USA, Canada, UK, EU, and Australia. As of March 2025, the ChompSaw was found to meet all of these standards!
These tests check for things like:
- No harmful chemicals
- No small parts that could pose a hazard for children ages 3+
- Durability to withstand everyday play
The rigorous third party testing follows official child safety regulations, including:
- US: ASTM F963 & CPSIA
- Canada: CCPSA Toy Safety Requirements
- UK & EU: EN IEC 62115 & EN71 (CE & UKCA certified)
- Australia: AS/NZS ISO 8124
Yes! The ChompSaw is designed to support hands-on, project-based learning for grades K–8. Our free curriculum is aligned with NGSS standards, so your students can demonstrate their understanding of grade-level concepts while picking up real building skills and spatial reasoning along the way.
