I would ask yourself how often you would need the other than the blade items found on a multi tool.
I didn't carry a multi tool for a long time, and found that the only things I missed were the pliars and screwdrivers which I need several times a week. I found the Leatherman Skeletool and it hasn't been out of reach since. It has just what I need and nothing more, and is light and flat (compared to any other multitool) in my pocket.
The knife is easily accessible with one hand and locks open with a liner lock.
