I have tried to use a screwdriver as an opener…

Posted by innovativeip on January 14, 2011

It is true.  I have tried to use a screwdriver both as a can opener and as a bottle opener, each time during that crazy first day or two after a move when you can’t find anything.  Although I don’t recall great success, I do remember successfully using a Phillips head to punch a hole in a soup can.  Necessity may just really be the mother of invention.

Actually, without knowing it, in reaching for a screwdriver, I was apparently regressing 100+ years.  Yes, today’s Patent of the Day is entitled “Screwdriver” but it sure seems to be a can opener to me.  What’s more, the simple design remains generally unchanged and is on the market still today.

U.S. Patent no. 981202, Issued January 10, 1911

Reportedly, the tin can was invented about 100 years earlier, in London in 1810, but a hammer and chisel were used for opening.  Seems I wasn’t so far off with my screwdriver after all!
