A curious little object from the past has recently taken the internet by storm — a strange, silvery tool that’s left most people scratching their heads. Photos of it have popped up across social media and vintage collector forums, accompanied by captions like, “Only 10% of people can guess what this is!” It looks like something out of an old sci-fi movie — part handle, part blade, part mystery. But this odd-looking gadget isn’t a relic from a laboratory or a workshop. It’s a simple, ingenious piece of kitchen history: the Presto Aluminum Cheese Slicer.

The Mystery That Fooled the Internet

It all started when someone posted a picture of the object without context, asking people to guess its use. The responses were wild. Some insisted it was a gardening tool. Others swore it was part of a sewing machine or a handle from an old car. A few guessed it had something to do with food — but even then, nobody could agree how it worked.
