Utility Blade Drag Knife

This is a Drag knife I developed for cutting Cardboard or thick paper products. I use it on my CNC table with 2 types of mounts. One for a router table and the other for a plasma machine torch attachment. It uses 608 2rs bearing and a 8 MM shaft standard for a 3-D printer parts supplier cut to length. I wanted a fully covered blade except for the cutting tip.
