Here is a handy little tool I have made to help me facilitate a bend in cardstock I use to make mock up templates for my sheet metal work. I get the card stock from sodacan boxes and it's nice and thick and there's plenty to work with.

The tool is run over the cardstock with a ruler as a guide, or can be used freehand for curves. Its purpose is not to cut, but to press in a crease or "fuller" which allows a bend to be made with out rumpling up the template.

It acts a little bit like a pizza cutter, but the disc is dull.


I opted to keep the handle as is from the forge since I put a good bit of effort forging in the rounded corners, but I wanted to do a nice file finish. I think they pair together nicely.
