The denim pen has a funny story associated with it.
When Eagle first made a denim pen he actually wrote a "quasi tutorial" for it. he sent it to me and I tried to make a pen using his instructions. Unfortunately I did not "read" his instructions correctly and only used a couple "wraps" of denim and the rest is CA. I believe we discussed that we could "turn a fart" if we had enough CA and the phrase was born "I think", as I never heard the phrase until that night and a couple months later he posted it on the IAP.
