Gridfinity Workpro Folding Utility Knife and Blades Holder

Workpro makes a nice three-pack of folding utility knives along with a box of spare blades. I like these because they are affordable, use standard box-cutter blades, and no tools are required for blade changes.

I carry these knives in a utility cart that I have decked out with a Gridfinity drawer and this 3 x 1 unit block holds all three knives and the box of spare blades that comes with them.

Mine is printed in Polymaker Electric Blue PETG filament. I chose PETG over PLA to avoid shrinkage in the variety of temperatures that my cart experiences.
