Last year my wife purchased some shun knives and I've been learning how to sharpen them recently. I purchased some wet stones and have been able to get them sharp, albeit not as sharp as when the professional sharpener did it. I'm not very interested in maintaining the blade. I do have a honer that makes a huge difference but in terms of using the whetstone, would it make sense to sharpen with a 6k stone when I feel the blade is dulling? I figured the 6k VS using 1k and 6k would save more metal on the blade. I've also found that using the 6k stone makes the knife much sharper than just the 1k - is this expected or just that my technique isn't great? I also recently purchased a sharpening guide rail to help me out - are these things useful?
