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.

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 3rd 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

Ages 3 to 103+!

We put the ChompSaw through all sorts of safety testing to guarantee our machine is 100% kid-friendly (which means it won’t cut fingers or snag on hair or clothes!). We’ve seen firsthand that different ages experience the ChompSaw in a range of ways.

Check out this blog post for a recap of our age-certification journey and how we’ve seen the ChompSaw work with one kid in particular (Milo, Max’s sweet boy) over the years!

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!
