    Mainly the angle changes wrt the application of the blade. Kitchen knives is normally sharpened to 20. I sharpen my upper class pocket knives the same. Normally pocket and outdoor knives are sharpened to 25. Carpet knives to 30, so I would recon that its also good enough for machetes. I used a Lansky standard set for many years but its a bit short for the larger kitchen knives. So I purchased a Ken Onion Edition Worksharp Tool and Knife sharpener.
    A lot of different sharpening methods would be effective. I guess that your oil stone might be having a lower grit (rougher) than P1000 sanding paper. P1000 is actually a good grit size for finishing a blade. I am still looking forward to inputs from other members.

    Peter, there are really only a couple of important factors to sharpening smooth-bladed knives:

    The first and most important is to keep the angle of the cutting edge consistent (and commensurate with the job the knife is expected to perform).

    Conseptually, the steeper the angle, the more robust the edge will be, but also the less sharp. So a machete will typically be sharpened to a blunter angle than a knife intended for cutting up ripe tomatoes.

    Practically, I suspect this is where you are going wrong. Keeping the angle consistent on a stone or water paper is quite difficult and requires lots of practice. This is why there are so many types of sharpeners intended to help guide the user to keeping a consistent angle, like the Lansky, the Warthog etc.

    The next is to sharpen the knife evenly on both sides, and if using an oilstone, to use the complete length of the stone. If one doesn't, it will become concave, making it practically impossible to keep the angle consistent.

    Lastly, it is beneficial to use graded sharpening devices as you are already doing, but 1000grit is far too fine to start off with. That's almost fine enough to finish up with.

    Couple of small tricks:
    At the start of the process, you can apply some pressure to the blade and also run it backwards and forwards. Toward the end of the process and on each grade, apply as little pressure as possible and work only forward. Don't drag the knife backwards. Also, at each stage, work untill you feel a "beard". Remove it in the next step.

    As for serrated blades, I have yet to find a method that works without gradually removing the serrations. I view serrated blades as throw-away items and avoid them as far as practical.

    What Peter said...

    Oil stones can eat a blade in the an effort to achieve a keen edge for the reasons mentioned.
    Warthogs are brilliant for their precision and ease of use, Lansky's are a bit more 'technical'.
    Personally I prefer my Lansky.
    You can tailor the angles of the edge to its intended purpose with very little loss.

    I personally use the Lansky to sharpen the knife the first time. Establish the edge. After that I use the warthog to maintain the edge. After a while I need to go back to the Lansky.
    A rough 600 grit will create a cutting edge microscopic serrated edge. The ultra fine stone on the Lansky is around a 1000 grit creating a smooth edge. For kitchen work it will last longer.

    The other thing most forget is leather stropping. For me this makes a huge difference
    The sharping steel is also very useful for straightening the edge

    Get her a nice bamboo one. That's my favourite. It's less creepy than wood. Not too pricey at the big PicNPay

    I am willing to help you. I have seen how the operators of Leatherman stalls go about sharpening knives and have never trust them and never will. I am in Mountain View. Your welcome to visit.
