A nice adjunct to any multi tool is some sort of small "sharpened pry bar"implement. I carry a County Comm widgy bar on my key ring and it is very useful for prying and scraping - the sort of tasks that will ruin the screwdriver blade on a multi tool. i don't use it every day, but when I need it, it works surprisingly well. There are lots of gadgets out there that will work as well - cheap enough that you can ruin them at no great loss.
