Abstract
In a die board for cutting and/or creasing sheet-type work material, a base is provided that includes a first upper surface and a second lower surface. At least one slot extends along the first upper surface and includes a first slot section extending from said first upper surface at least part-way through the die board base. The at least one slot also includes a second slot section extending from said second lower surface at least part-way through the die board base. The first and second slot sections each have a width with at least one of the slot section widths being adapted to grip and retain at least one die-board rule.
