This 12 in 1 multi tool is fantastic! It has a case that can be put on your belt to carry it so you will have it any time you need it. It is great for your car or when camping. I am going to keep it in my car so I have some tools when I need them.. The knife is sharp, but will get a better edge on it by the time i am done! This is a very well constructed tool, and allthe tools are easy to pull out. Even my husband with his huge hands did not have any trouble with them. He actually stole it form me and has declared it his new favorite tool.. I guess I will have to get another one! Since he does a lot of woodworking I guess he figured this could come in handy. It has a hammer (well weighted for easy driving) it has a nail puller that actually should hold up well under pressure, a file and a knife, a philips and a slotted screwdriver and a saw. This also has a bottle opener.. great for emergency needs if you are in a car also!
