I've thought about using a bag, but then i'd have to remember to grab it every time i went somewhere and i'm sure i'd forget it somewhere. carrying a bag is not very convenient. For instance, if i go to someones house to fix their email, I may not need any tools, it would be kind of ridiculous to walk in carrying a backpack. I'd be trading in my full pockets for what essentially ammounts to a purse, which doesn't sound appealing to me. that is a great analogy. I never used to carry this much stuff with me a few years ago, but i find myself in a situation where i need a tool to fix something and i have to go searching for one...that is when that item gets added to my EDC, assuming it is practical to carry such an item. Over the years, i've built it up to a very extensive list of stuff, but its only because i've had a need for this stuff in the past. Just like a spare tire.
