Plastic board and cutting mat: Create a stable surface for cutting by fitting or securing a cutting mat onto a plastic board. Ruler with holes for knife entry: Secure a ruler (or a tool acting as a slider) with thin holes on the plastic board where a knife can fit. Left and right movement: Use a fixed device to allow the ruler to move left and right, enabling it to be positioned where desired during work. Up and down movement using springs: Attach springs to allow the ruler to be moved up and down, so it can be lifted or lowered when needed. This should facilitate easy movement of the ruler and performing cutting tasks with a cutter knife.
