Obviously fire has a plethora of uses, warmth and drying, protection, purifying water etc. And yes, a lighter is a great way to start a fire, particularly when you can run down to Walmart and buy a package of Bic or Bic clone lighters for very cheap. I think I bought a package of 8 or so Bic-style lighters for $1.99. However, the ability to make fire is an area I really like to be redundant. Harbor Freight has the magnesium bars w/striker for less than $3 and sometimes on sale for less than $2. Each could literally start thousands of fires.

Here is some firesteel.com videos. The sparks are suppose to be around 5500 degrees F. And as you can see in the video, a cotton ball with vasaline or chapstick makes great tinder as well as steel wool.
