Hi, I have been spending a lot of time trying to decide which knife set to purchase. I think I have finally decided on the "Wusthof Classic Ikon 7-piece Deluxe Knife Block Set" http://www.cutleryandmore.com/wusthof-classic-ikon/deluxe-knife-block-set-p120293 Now I am unsure of which sharpening stone to purchase for it. I was looking at Wusthof ones, since I am buying Wusthof knives, but that probably doesn't really matter. I just don't want to ruin these knives. I use whetstones at work, but am unsure of the grit# of it because they are so worn and used. I was leaning towards this one http://www.cutleryandmore.com/wusthof/combination-ceramic-water-stone-base-p16011 because I think the 400 & 2000 grit sounds good. Also, it looks like the one I use at work which I am comfortable using. But than there is also this one http://www.cutleryandmore.com/wusthof/fine-combination-ceramic-water-stone-base-p113930 which is 400 & 1000 grit, and also comes with a cool case. http://www.cutleryandmore.com/wusthof/tri-hone-water-stone-sharpener-p131660 Seems pretty cool too, but I'm not sure if I like the low 240 grit. I feels like that might eat away too much on my blade. But the extra 1000 & 3000 grit seem pretty cool. Also on that cool little triangle thing. Anyways, just looking for some feedback. Thanks!
