Use to score or cut thin to medium material (cardboard, thin plastic, balsa wood, etc) in nice straight lines of the same distance / thickness over and over.

Loosen the screw on the slide mechanism, adjust to the size board you would like, then tighten down.  You can then slide the tool along the edge of the material to make your cut.

You will need

• A blade, similar to an Xacto knife,
• 3 M5 Bolts and Nuts, length not important, but I used around 5 or 6mm

To assemble, the most complicated bit is tapping one of the nuts into the base, which can be done by screwing the bolt in slightly then tapping it with a hammer.
