Utility knives in an elementary makerspace?
Our position, and other voices worth reading before you decide.
Our position
Do not buy them for the makerspace. If the school already owns them, they live somewhere else.
Every adult's first instinct for cutting cardboard is a box cutter. It is the tool we grew up with, so it feels normal. In a classroom it is a liability. A utility knife only cuts by drawing it toward soft tissue and has zero safety design against an 8-year-old who grabs it off the table.

Makedo - Why Safe Saws
Broadly agreesMakedo's whole premise is that purpose-built safe saws for kids replace the utility knife in elementary cardboard work. Their educator resources lean hard on this point.
The Chomp Shop - ChompSaw safety pitch
Broadly agreesThe ChompSaw was designed specifically because existing cutting tools (utility knives, scissors) were unsafe or ineffective for elementary cardboard work. Their product page lays out the safety-vs-capability argument directly.
Exploratorium Tinkering Studio
Broadly agreesThe Exploratorium's tinkering guides avoid utility knives in favor of saws and templates for cardboard work. Browse their cardboard automata and construction resources.
Instructables cardboard community
Nuanced / mixedThe broader DIY community uses utility knives routinely on cardboard projects. For adult makers this is fine. The question is when kids enter the picture - browse the classroom-tagged projects specifically.
Adult DIY / model-making community (general)
Pushes backAdult hobbyist communities (model-makers, cosplay, prop-building) treat the X-Acto and utility knife as core tools. The argument against the knife for kids does not translate to 'the knife is bad' - it translates to 'the knife is not for kids.'
