I used to carry one of those little folding can openers. They're really light, and really small, but after going through my gear list over and over I realized I'd probably never use it again, so it sits somewhere on my shelf with other old gear.

That guy carried a BIG can of beans too. I couldn't believe it when I saw it, but it wasn't the only heavy stuff some of those guys carried. One carried a big steel wok, and they had steaks and potatoes and onions and eggs and sausage and all kinds of heavy food and drinks.

They were glad to share it, and I was glad to have a share. Luckily I was able to share a few things too. Not much, but I had salt and pepper, and I brought way more instant coffee than I needed and they were really short on that, and I pulled out a few other niceties to share, so it worked out pretty good for all of us
