Manual Slicers: These typically have a handle and a set of blades. You place the tomato on the slicer, press down, and the blades slice through the tomato.
Adjustable Slicers: Some slicers allow you to adjust the thickness of the slices, giving you more control over how thick or thin you want your slices.
Electric Slicers: For those who slice tomatoes frequently, an electric slicer can be a time-saver. It usually comes with a motor that makes slicing quicker and easier.
Tomato Corers: Some slicers come with a coring feature to remove the stem and core of the tomato before slicing.
