Steptoes Dog Antiques has a small selection of Vintage Egg Slicers currently available to buy on their website. Vintage egg slicers do look pretty much the same as modern egg slicers, but if you really want everything in your kitchen to be retro, then here is the place to buy your egg slicer!
At the time of writing there are two egg slicers from the 1960s, in bright green or orange plastic,and an aluminium slicer dating back to 1938, all complete with their original boxes. There is also a white egg slicer from the 1970s that does look rather different from the others, but that does not have a box. Prices range from £9.54 for the 1970s one, £14.14 for the 1960s versions up to £21.04 for the 1930s slicer.
