Wiel Stuart, former miner of the Oranje Nassau mine II, invented and made the original Twisty at an advanced age, when his hands became less strong. He was inspired by the metal belt wrenches that were used underground to loosen and tighten oil filters in heavy machinery.
Robbie Greve, grandson of the inventor, has significantly improved the model: thanks to the round head and the combination of short and long loop, all sizes of (screw) lids and caps can now be opened a lot easier.
Minke Greve-Stuart found the original version of the Twisty-opener (made by her father) in a drawer in her parents' house at the end of 2018. She found it so useful that she decided to market it. A year later she designed the Twistyholder to ensure that even people with very weak hands or with only one hand can open all screw lids and caps.
