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!

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!

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

Yes! We currently stock replacement cutting heads (linked here) that you can swap into your ChompSaw at home! If you need a refresh, or something else, our engineers are always happy to explore getting you one-off spare parts. Email us anytime at hello@chompshop.com

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.

The ChompSaw measures approximately 10 inches long, 10 inches wide, and 4 inches tall, with a weight of 5.5 lbs.

The power cord is stored under the lid of your ChompSaw. Simply lift the lid to locate it!

The ChompSaw runs at about 70–75 decibels, which is roughly the volume of a household vacuum. We've done the proper safety testing to ensure our machine is safe for kids’ ears, but understand that the noise can feel a little loud.

If your child is sensitive to sound, we recommend using ear protection to make the experience more comfortable. A lot of kids actually love wearing safety gear like earmuffs and goggles. We've found it helps them feel like real builders and makes teaching power tool safety a fun part of the process!

If you’re noticing your machine slipping when you push cardboard through, the cardboard might just be a bit too thick! The rounded part of the little wooden scoring tool we sent works wonders for compressing the area where you’d like to cut, making it easier to feed thicker pieces through the machine. We’re also working on a long-term solution for slippery surfaces that sometimes keep the ChompSaw’s rubber feet from getting a good grip. In the meantime, a little double-sided tape or a non-slip mat is a great quick fix!
