Today's tool is another interesting one- originally called the Ta-Bar tool after it's designer, Raleigh Tabor, the name was changed to the Spare Tool for production so as not to upset another well known knife brand!
Sometimes the simplest designs are the best, which explains the myriad of one piece tools on the market these days. The Spare Tool follows that example in spirit if not in form. Technically it has more than one piece in the design, and is somewhat larger than the average one piece tool like Atwood's Prybaby, Gerber's Shard or Raker's Ring Tool. However, it does fit the pattern of a basic prybar, bottle opener and a few other functions rolled into one basic piece of steel like the others.
