Can't go wrong with a Wusthof. I had researched automatic and 3-stage sharpeners. I was leaning towards a 3-stage util I happened upon this. The coarse and fine sharpeners do the job, though I've only had this for a short while. Time will tell.
I followed the instructions for this knife sharpener and used it on my steel knives. The instructions said to run the knife through the sharpener 3 times and to try a paper test to check its sharpness. I obviously had very dull knives and had to run them through the sharpener at least 10-12 times before I could pass the paper test. So, this product does work, but if you have really dull knives or if cooking is your profession it might be better to have your knives professionally sharpened.
