Question: Has anyone compared this to the Swissmar Mandolines from Germany?  Thank you.
Document: Very handy and professional slicer especially for everyday use(home or at work).Very recommend .Great buy, long for ever.Thank you
This machine slices with such ease that at first I thought it wasn't working, until I lifted it and found a pile of beautifully thin sliced onions! Use it everyday ! Thank you
I don't let anyone in my family use it other than me for that reason.
Because this thing is SHARP. Absolutely amazing and a steal compared to the fancy brands that cost upwards of $100. New favorite kitchen tool.
Very sharp blades, excellent product, I would recommend to anyone.
I've had similar devices before, and this works as well as any I've used. I would recommend it to anyone.
The blade on the Benriner Japanese Mandoline Slicer is fantastic. Cuts with ease and accuracy- especially compared to less expensive models that I have used in the past.
This product is great for all of my salad and rawfood recipes. I wholly reccomend it to anyone who loves to create different things with their veggies.
This was sent to a friend of mine as a thank you gift and I think she will love it if she can figure out how to use it. I just heard back from her last week and apparently the directions for usage are in the Japanese language. She was going to try to have them translated! I am wondering if you are aware that the directions are only in Japanese.
This product is good quality and a lot easier to use/clean than other brands of Mandolines. I also recommend the wide version of this that is handy for things such as apples and eggplants that have a wider girth.
Answer: The V blade tends to bind up, which forces you to apply more pressure that results in injury. Japanese mandolin is the way to go.
