The time you find yourself doing emergency trail repairs tends to be the worst possible time. It's getting dark, it's pouring rain, you've got a bunch of friends standing over your shoulder waiting on you, the list goes on. The only way to make it worse is to work through that repair with unfamiliar tools.
When you get a new multi-tool, spend some time really getting to know it. Go through all the tools and see how they work. Check out how it opens and how you use each tool. If you are doing maintenance in your home, consider grabbing tools out of your portable kit for a while. The tools you have at home are going to be easier, and more comfortable, to use. Before you switch to those though, make sure you've gotten really comfortable with the multi-tool you bring with you.
