Mat Knife (with blade storage drawer)

thingiverse

I teach students how to create stunning visual displays through projection mapping. As part of this hands-on class, they learn to build scale models of venues out of foam core and poster board. To bring these models to life, I need a specific type of knife - one that can bevel the foam core with precision. I opted against buying a separate mat knife with a different blade, since I already have dozens of x-acto blade handles in my collection, along with hundreds of spare blades just waiting to be used. When installing this new blade, keep in mind that it should make a cut 1cm from the edge of the holder for optimal performance.
