I have always wanted to develop my own drag knife to cut cardboard, wood veneer, paper etc... In this video I 3D print and test a prototype and then mill the final working knife out of aluminum.

I figured I had better add a mechanism for sending out the cadwork for the Drag Knife since there has been so many people asking for it. I though this might be an interesting approach!

Please allow 24 hours for me to send you the files!

The bearings you will need are 1/2" ID X 1.125" OD bearings found here...
