Here is your new 11 functions in 1, lot of 3 credit card pocket survival tools. Made of stainless steel, what stands out, to me, is the saw blade function. There are 2 offset rows of teeth. It is really sharp. See the second photo for all the functions by name and the main photo for identifying where each one is within the multi tool. Also, see the specs above for more detail. Whether your a serious survivalist, or a weekend hiker, you need this tool as part of your gear. Thanks for stopping. Please visit my slow growing store for other outdoor items and to read about me, my policies, as well as browse. David - thediscountretailer
