My husband and I have been traveling for years to do volunteer work abroad. Each time we try to get a new tool or something that will help us with our work. The most used tool has problem been his Leatherman (a multi-functioning pocket tool that is very durable.). But what would you suggest be the ultimate tools to have if you were going to travel abroad for either short term trips or long term trips? We are always looking for new ideas as it seems no matter how much we prepare there is always some tool we wish we had with us.
