Step 4: Try it out.

Picture of Try it out.
Now just get your piece of corrugated, and mark a line where you want to bend it.  Start with the tool rocked up on one end of the line and roll it down the line. that's it!
If you need a longer fold than the tool, just move it over and start again.
Now that you have it creased, just grab your cardboard and fold. NIce straight clean bend every time.

I too enjoy making things from cardboard (free is good). I've always used a creasing tool and straight edge. That is hard work. Your tool is much better. Thanks for sharing this.

Neat idea! Since I'm lazy, I might try gluing a length of solid bare wire, maybe 14 gauge, to the curve, instead of forming the "v". The wire pressing into the cardboard won't make quite as sharp of a groove, though.

You helped me solve a problem I didn't even know I had, thanks! I'll be making this soon.
