Celebrating the 131st anniversary of the hole punch, Google on Tuesday dedicated a colourful doodle to the essential office tool.

The doodle features every letter of "Google" except "L" created out of discarded colourful paper discs eliminated out of hole punch. Though the hole punch was invented a century ago, nothing much has changed in its outlook.

Google's blog post on hole punch wrote: It's a familiar scene with a familiar tool: the gentle rat-tat-tat on the table as you square up a dangerously thick stack of papers, still warm from the printer. The quiet anticipation and heady uncertainty as you ask yourself the ultimate question: can it cut through all this? The satisfying, dull "click!" of the blade as it punches through the sheets. The series of crisp, identical holes it produces, creating a calming sense of unity among an otherwise unbound pile of loose leaf. And finally, the delightful surprise of the colourful confetti byproduct “an accidental collection of colourful, circular leftovers".

Google refers to hole punch as an "artifact of German engineering". It  credits the invention of the hole punch to German inventor Friedrich Soennecken. He devised a tool to make small holes in paper. Later hole punch was patented by Benjamin Smith, who named it "Conductor's punch". In 1893, Charles Brooks patented a paper punch and called it as ticket punch, reports Thoughtco.com.

Later, the hole punch became popular across the globe, it was used for various purposes.
