Open a Stuck Jar With a Knife





Introduction: Open a Stuck Jar With a Knife

Jars can be troublesome little jerks. They're stuck tight and you're stuck trying to pry them open with your hands.

To make them easier to open all you need is a regular table knife. No fancy tool, no extra junk to fill up your kitchen, just a few hits with a knife.

For those who want TWO ways to open a jar with a knife, here's part 2.

Step 1: A Few Whacks

To loosen the jar is just a matter of three or four hits on the lid with a knife so you get some dents. These dents loosen the seal and make the jar easier to open.

To be more precise, do this:

  1. Hold the back of the knife against the jar at a 45 degree angle
  2. Pull it back a bit
  3. Whack the back of the knife hard against the corner of the lid so it leaves a small dent
  4. Repeat 2-3 times around the lid
  5. Open

Step 2: What Success Looks Like

In case you're wondering just how big of a dent is appropriate, here's a close up shot. You should be able to catch your fingernail in it.

Jars can take a pretty strong hit. I've never had a jar break while doing this and I've done it hundreds of times. Check out the video in the intro to see how much abuse a salsa jar can take.

    Does this technique work on plastic jars and lids too?

    I was taught this way over 50 years ago by my grandmother. back then men were at work while women stayed home to open jars.

    True story... my grandmoter was a professional jar opener. She was hired by IBM in the 30's. back then, IBM produced peanuts for elephants who were the country's main form of public transportation. The company would import hundreds of peanut butter jars from Amsterdam and my grandmother would spend all day opening the jars and handing them off to the Peanut Assembler, who would reassemble the peanuts for packaging. In 1934, my grandmother was invited to England to meet the queen, as she (my grandmother) had opened her 5 millionth jar. In 1940, my grandmother lost her job as the country abandonded elephant transportation in favor of porcupines... and, as we all know, porkupines don't like peanuts.

    I would like to hang out with you. More stories please!

    how does one reassemble peanuts from peanut butter?

    lol, sounds more like empty peanut butter jars?

    This seems a little far fetched but because I didn't know your grandmother I'm going to take your word for it ;)
