Question: Can I use it to peel potatoes?
Document: Just to hedge my bet on my next potato and carrot peeler I ordered this along with the OXO Good Grips Y Peeler reviewed below. Frankly, this won out. Probably no sharper or faster but I like the ergonomics of this better. It feels like the way you naturally hold a knife (which is how one used to peel potatoes).Very comfortable to use.
If you want to peel a tomato without scalding or stretching the skin this is the peeler to use. The serrated blade slices thinly removing only the skin. This would make a great gift for anyone you know who still peels a tomato with a knife. The handle is comfortable and makes for easy control. The eye remover on the end is great for potatoes.
I use it for any type of peeling, potatoes, tomatoes etc... works great. It is sharp so be careful! Every Zyliss product I have purchased has been exceptional.
This works great on soft fruit like pears, and just fine on anything else like apples (hard or soft) or potatoes. I don't know that there's a reason to buy the straight edge version. Both versions tend to cut too deeply for my taste, but that's not a big deal when pealing pears as nothing else I have works so well.
This is the best peeler I've ever used. Not only on soft skin fruit and tomatoes but also carrots and potatoes.
I use it to peel tomatoes, it is great! Use it you, if you dislike skings, will love to use it,
Wow! This really works. If I have a quart of tomatoes to peel, I'll still use a water bath--but for just a few tomatoes, this is much more efficient.
It sounds impossible, but this little trick seems to get sharper with use. I bought it to peel tomatoes. It worked great. My wife has used it on peaches with great success.
Love the shape, easy to hold, Peels with ease, best peeler I have ever owned. I use if for more than soft skins. Almost look for something to peel just for an excuse to use it!
I got this for me and everybody got one for Christmas. It is easy to use, it really does peel a tomato! For carrots, it takes a very thin (wafer thin!) slice of peel, great with organic carrots that don't need much peeling. I think you will love it too.
Answer: It has a serrated edge and that's why it works so well on soft things I think.   I suppose you could do cooked potatoes with skins on to peal them.  I can say I love it for tomatoes !!!  skins are too tough for me so I peel them and love them raw that way.  I bought several for gifts and they all seem to like it.
