Design & Operation

kyoceradoubleintrocrop Like Kyocera’s other hand-held slicers, the Double Edged Mandoline Slicer is shaped like a small paddle and is molded of very lightweight plastic. Measuring 11″ long (just under 28cm) by 3 5/8″ (9.3cm) wide overall, the usable width of the cutting deck measures 2 7/8″ (7.5 cm) wide.

This model is unique in that both sides of the ceramic blade are sharpened, so that it makes 2mm cuts on both the downstroke as well as the upstroke, effectively doubling processing time. We noticed that the blade on this model is fixed at a different angle than Kyocera’s other hand-held models (we measured 67° vs. 57° for both the Adjustable Mandoline Slicer and the Julienne Slicer). We guessed that the flatter angle was necessary in order to provide sufficient real estate below the blade without increasing the overall size of the device.

Performance Tests

Slicing long, cylindrical vegetables and fruits like zucchini or cucumber is the raison d’être of this Kyocera, and it excels in this capacity. Processing speed is incredibly fast and slices were consistent and intact.

This cucumber was neatly taken apart in under fifteen seconds.


The Kyocera cut through the potato easily and produced quite consistent slices. However, readers should keep in mind that the non-adjustable thickness might not be suitable for all applications.

While processing was twice as fast, we did notice that slices were not as consistent edge-to-edge when compared to another Kyocera model, the Adjustable Mandoline Slicer (when set to 2mm, to match the Double Edged Slicer). However, we believe the difference will not be apparent in most finished dishes.

In general we have found that Kyocera’s ceramic blades are not as good as steel ones when slicing tomatoes, so we were not surprised when the Double Edged Mandoline Slicer struggled on this test, considering that 2mm is extremely thin for slices of tomato. We felt that this task fell outside the intended usage of the device, however, so did not consider its score in this test when determining its overall score. kyoceradoubletomatocrop


The model was ineffective in cutting through tough lemon skins without tearing them. Again, we attributed this partly to the model’s ceramic blade. However, considering that this model did not perform as well as Kyocera’s Adjustable Mandoline Slicer, we began to think that the shallower blade angle of the double-edged model was also playing a role in its poor performance. This was another task we considered to be outside this model’s intended scope and we did not include it in our overall scoring.

Safety Features

During our testing, we found that the single greatest factor in determining mandoline safety was how much pressure was required to feed produce through the blades. In this respect, the Kyocera was outstanding, requiring significantly less force than most other mandolines we have tested.

The included hand guard feels like an afterthought and is rather poorly designed. We found that the small plastic spikes on the underside of the device were ineffective in securing most produce. However, for the type of slicing tasks that this model is designed (cucumber, zucchini, etc.), we did not regard the lack of a good hand guard as a serious issue and felt comfortable processing foods by hand.

When using any mandoline we recommend the use of a cut-resistant glove.

  • produces clean, consistent 2mm slices of most fruits and vegetables
  • double-edged blade halves processing time
  • very easy to clean
  • fixed 2mm depth will not be suitable for some applications
  • failed to produce acceptable results with lemons and tomatoes

The Kyocera Double Edged Mandoline Slicer is a special purpose tool designed to make thin–2mm–slices of fairly small diameter fruits and vegetables such as cucumber, zucchini, fennel and potato. Its double-edged ceramic blade slips through most produce with ease and churns out neat slices at twice the rate of conventional mandolines.

This Kyocera earns our recommendation for performing its intended function extremely well, but readers should also be aware that it does not possess the functionality of some other hand-held slicers. First, this Kyocera is not adjustable, meaning that it will not appropriate for all tasks. Second, it performed poorly on our lemon and tomato slicing tests. As long as readers are aware of these limitations we believe they will be very happy with the speedy performance of this model.
