"THE PERFECT GIFT"

(205)

My newly six year old boy played/created for two hours on his first day and asks to use it everyday. It’s simple yet engaging enough of a tool that keeps his interest. Everything is easily set up. It will be a great tool for many years!

"SO MUCH FUN. MY SON LOVES IT!"

(205)

We’ve had so much fun creating! We’ve made knight’s armor, a crown, and a rocket to start! I love how my son comes alive with creativity when he uses his ChompSaw!

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

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 (it won’t cut fingers or snag on hair or clothes!). It doesn't matter how many candles are on your cake, building something with your own hands never gets old!

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 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!
