How Long Does it Take to Max Out EVERY Weapon in Dark Souls?

Today we embark on a journey to acquire and upgrade every single weapon in the game! Will I lose my sanity along the way? Find out! Just btw, I apparently deleted a couple of sections here and there (the winged spear, getting the Obsidian Greatsword, and getting the Gold and Silver Tracers). Tends to happen when you have over 200 video files for a project!
