I bought a tool similar to the Gerber shard for hubs a few years ago and he never really used it. Now we both have snowflake multi-tools in our bags - FA used hers to try to help me fix my tray table and we loved it (tray table unfixable but we loved the multi-tool) Not for dining, but handy to have.
@cdtraveler - that's why we travel with utensils as well - I love to eat from markets when we travel. It started when we were young & poor & traveling where we could on a budget, now I just love to do it to get a better sense of where we are!
