Input:
Question: Would you use this for a set of carbon steel Wusthof knives? I have a few of those, made in Germany, love them and in need of sharpening.
Document: I'm amazed at how this little sharpener has restored my Global knives to the same sharpness as when they were new. It is very simple and safe to use. I have been using the ceramic wheel sharpeners and they cannot get my knives to anywhere near the level of sharpness that this one does.I would highly recommend this sharpener to anyone who uses Global knives.
I have a set of global knives and this is a great way to quickly sharpen the knives when a wet stone is too much trouble.The product arrived quickly, direct from Japan, and JAPAN IMPORT even included a small origami bird as a thank you.
I am disappointed in this sharpener....it didn't seem to work nearly as well as my previous Chef's Choice for my Global knives. It is quite small also:  4 inches. I'm not sure if it is really made by the same company that actually makes the knives.
Typical Global quality here: solid and simple. It's not as cool as a steel but it costs about a seventh and sharpens your knives in just a few swipes. Get this and your knives will always be sharp in a few seconds.
My Global hadn't been sharpened in 1.5 years and this puppy made it razor sharp with about 12 swipes through the stones.
Answer: I bought it as a gift and haven't used it. From what I understand global knifes are shapend at a different angle than German knifes. It wouldn't be ideal.
