This is my third Victorinox Swiss Army knife.  (I lost the first and still have the second.  I only bought this because I wanted more tools).  These knives are incredibly durable.  I've never had one fail me.  With some imagination, the tools can be used for many more things than their intended purpose.  They are also much smaller and lighter than a Leatherman or similar tool, which makes them convenient to have on you at all times.  They're perfect for those moments when an unexpected need arises and you don't have full size tools with you.
