I use a metal scribe that has been dulled to score lines with. I have tried to use the back of my x-acto knife as was suggested to me when I first started building paper models, but it didn't work. I kept cutting through the paper. Also, I use 1/8" hardieboard as a cutting mat. You can get it in...

micahrogers posted the original pdf ..... I just modded it for myself. If he is ok with it.... I will post...
