Question: How do you adjust the blade?
Document: I absolutely love this slicer! The blade is ultra sharp, and is very easy to adjust for different thicknesses of slices. I also like the fact it's red!
Arrived quickly and in perfect condition. I've only used it twice, but so far am very pleased. It took a few minutes to figure out how to adjust the blade for different thicknesses, but seems to work fine.
I love this mandoline, especially how easy it is to adjust the thickness of the slice. I had one for about 4 years and the blade was just as sharp as the day I got it, but had to replace it because the handle broke off near the body of the mandoline.
I use to have a great easy-to-use slicer. It fell apart. I greatly miss it. I wasn't adjustable, though, and this is to four positions. it''s easy to adjust and the ceramic blade is very sharp. Best of all, it doesn't rust or discolor.
Very sharp and slices well. I gave this 4 stars because I would like to be able to adjust the blade more. You have two options, very thin and then a little thicker. I don't regret purchasing this, but would like to find one with more thickness options.
A great tool! Definitely need to be careful as the blade is VERY sharp - I chose to hang it on my wall rather than keeping it in a drawer so that I don't accidentally cut myself. It works really well, and the various sizes you can adjust to are great for a number of different purposes.
I have lots of mandolines. Most are a bit cumbersome to set up. This mandoline, the Kyrocera is my all time favorite! Very easy to use, easy to clean, the blade stays razor sharp for years! It will be hard to beat this mandoline for its value and practicality. The slice thickness is super easy to adjust. Get one, you will not be disappointed.
I LOVE this slicer - it was inexpensive so I didn't have high hopes for it (despite the good reviews) but I have to say that it works great, specially if you consider its low price. I find it very easy to clean and the fact that you can easily adjust the hight of the blade makes for very easy changes to what you want to slice. I use it so much more than I had expected because it is small, works well and does not require complicated adjustments.
The thinnest setting works superbly. Was unable to adjust the setting to any other thickness so if that option is important to you, don't buy this one.
I do not know how to adjust this slicer. I see no way to adjust the slices so I have not used it. Please advise there were no instructions with it.
Answer: There is on the back a 4 sided bar that you turn to vary thickness
