Thread: Sharpening Issues...(if you are sensitive to bad sharpening, please avoid this)

    Sharpening Issues...(if you are sensitive to bad sharpening, please avoid this)

    Hi everyone

    I been working on my skills with waterstones and I think I am making some progress and my knives are pretty sharp but I have an issue.

    It seems after the edge, other parts of the knife develop this muddy looks. Please don't mind the scratches, they were there ways before; just not the muddy look.

    The best look near the tip

    Here is my progression: 240grit (or 120 if needed) to grind away the bad and set the edge and then use 500 grit and 1000 grit to refine it and smooth it down

    Then I use green brick to sharpen/prepolish and finish with 6000 for mirror like edge.

    I am thinking that my angle maybe too low but if I raise it, in past, the blade would catch on the stone (even in slurry/water).

    I would really like to learn how to do it myself on waterstones

    Thanks for the advice

    Which angles did you use?

    You clearly have a bevel. It is a compound bevel but a bevel nonetheless. I would take a magic marker and draw lines from edge to spine along the entire length of your knife. Make one normal pass on the stone. I wouldn't bother with the sub-500 grit stones, either. Use a finishing stone. See what you're hitting. I think you're just wildly inconsistent. I don't understand how you get a bevel at all, lol. Anyway, keep on doing the marker thing until you're only hitting the edge. It will take a very, very long time to refinish the side of the blade on stones. I would recommend you use a block of wood with some spongy material on it and sandpaper on top of that. Rub it in one direction until the finish is even-looking. Go up in grit until you're satisfied with the size of the scratches. Do you flatten your stones, btw?

    Hey Ptolemy, my advise from one rookie to another, though caveat emptor, this advise may be frowned upon by the experts.

    Stack 4 pennies on the near end of your stone. Set the edge of the spine on top of the pennies. Slowly sharpen per usual trying to just graze the top penny with the edge of the spine. Do this until you get a burr then flip and do the other side. This will help you be more consistent with hitting your angle and help you develop muscle memory. Works for me at least.

    As to your scratches on the rest of the knife, you'll have to do as tk59 said and sand them out.

    Another variation is to sharpen sectionally with the spine toward you and switch hands so you can always keep an eye on the height of your spine to keep your angle constant.

    I have told my family members to use the plastic slide from a report cover to slide in the spine of the knife.
    Only thing you have to worry is to make sure that it is lifted enough away from the stone for the desired bevel angle.
    One like this.


    It is the same/similar concept to having a clip on guide that is sold.

    Not sure I understand what the problem is...

    I was trying to figure it out also, I will go out on a limb and say that he does not understand why the blade gets cloudy during sharpening, and if it is because of his sharpening angle. Or, what causes this cloudy finish on his blade when sharpening.

    If it is not either of these, I'm still in the dark.

    What is the blade made from?
