Input:
I used to use a Spyderco sharpener which provides great results, when used correctly.  This does almost as good of a job at a fraction of the time.  I don't know enough to tell whether or not it is doing any long term damage to the knifes or not but it does put a very nice cutting edge on my Wusthof's.

A: very positive
B: positive
C: neutral
D: negative
E: very negative
Answer: B: positive
