A small hand mandoline for producing even slices quickly, sized for the things a full-width model handles badly: radishes, garlic cloves, a single shallot, a piece of ginger.
Blade: stainless steel.
Thickness: adjustable, selected on a quick dial set into the handle.
Guard: a safety guide grips smaller pieces so your fingers stay away from the blade.
Grip: soft and non-slip.
Changing thickness is a turn of the dial rather than a swap of parts, which means you can go from a fine slice for a salad to a thicker one for roasting in the middle of preparing the same dish.
Even slices are not only about looks: pieces of the same thickness cook in the same time, which is the difference between a tray of uniformly crisp vegetables and one that is half burnt and half raw. Compact enough to store in a drawer rather than a cupboard.
