Mono Monday ...Sweden

You learn something every day....thanks Heanku, a tough challenge.

The modern-day zip – or zipper, if you're American – as we know it was improved upon and developed by Swedish–American inventor Gideon Sundbäck from an earlier less effective model in 1913.
Sundbäck’s newly redesigned version called the ‘separable fastener’ was patented in 1917 and features interlocking teeth pulled together and apart by a slider.
