Last week’s mystery item drew a huge range of wild guesses and detailed explanations from many readers.
Dr Willem Halm, Rod Hewer, Stewart Edwards, Glenn Miller and Jane Hutcheon were on the money with a dental press.
The heavy-duty gadget is used in the making and repair of dentures and orthodontic apparatus such as retainers.
Other suggestions included a golf ball press, a clamp used for vulcanising a tyre’s inner tube and a brand seal.
Food-related theories were popular too, with Peter Willis, Steven Vickery, Helen Millar, Heather Henderson and Lesley Grano suggesting a nutcracker, while others thought it was a tongue or duck press, or even a Communion wafer press.
