Works for custom boxes, forts, sculptures, and toys you design yourself

You can build custom cardboard creations with perfect joints when you have the right cutting tool. This slot saw cuts clean, tight slots that match standard single wall cardboard thickness, so your pieces lock together smoothly without gaps or glue.

The blade is shaped to cut a 4mm kerf that lines up exactly with cardboard width. You slot two pieces together and they hold. Make shipping boxes that assemble flat. Build cardboard forts and sculptures. Create toys and prototypes. The saw handles all these jobs quickly because the blade is designed just for cardboard, not for wood or plastic.

Your tool comes ready to use. The end is blunted on purpose so you stay focused on cutting and making, not on safety concerns. This is a 3D printed workshop tool made in the USA from durable materials.
