I've found uncoated stainless steel is a very durable material choice for mods to be made out of, though I haven't seen it often outside of tube mods, and even less for the entire box. It's much more dent and scratch resistant (since it's harder) than other metals commonly used such as zinc alloy, aluminum, or zinc/aluminum that's been plated with a "stainless" finish (most advertised as "stainless" are plated to save cost, so as soon as it's scratched it can't be fixed). If by chance it does get scratched, it's easily fixed with some high grit sandpaper and polish. I think this makes it ideal for a daily carry mod that could see some abuse, but can still look great at the end of the day. I'd like to start a thread detailing any box mods where stainless steel is the primary metal used for construction (the more the better) for those looking for a durable box mod, though it's fine if there is some plastic, wood, etc. mixed in where it would normally be gripped in the middle. Please feel free to add any more that you know of! Edit: Now that I think about it, bonus points for any box mods made out of titanium (same hardness but lighter than stainless, though usually very $$$)!
