Promising review: "I rarely use tools, but on the rare occasion that I need one, I groan thinking that I need to go buy the respective tool. This multi-use pocket tool is just what a gal like me needs! The best thing about it is that unlike other multi-tools, it is flat and fits in your wallet! They also provide a carrying case so you can store it in your bag. They advertise a keyring hole, which is the one thing I would advise against, because the knife edge and saw blade are sharp and I wouldn't want this tool hanging around my body. But on the bright side, with the stainless steel material, the tools are actually sharp — a pleasant surprise. This won't break with average use." —Johann Christine Alcaraz
