Is a mandoline slicer patented?

Short answer: specific designs of a mandoline slicer have been patented many times, but "a mandoline slicer" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a mandoline slicer been patented?” but “has my combination of features been described before?” Kitchen gadgets are a crowded, mature field; novelty usually sits in one specific mechanism, the material, or how two familiar functions are combined.
