    Pushing hard just isn't ever a good idea when sharpening. Sometimes it helps you remove material faster but everything else suffers: edge geometry, stone.

    I start on the backside using a 1k stone (ONLY) for initial sharpening then use only polishing stones. The 1k has to be used EXTREMELY light handed too! The reason I do this is to set the bevel to the cutting edge because almost always a new knife comes without a flat bevel on the backside.

    AGAIN - only use the 1k on the initial sharpening - use it very lightly - do just enough to get the bevel set up correctly and then use only polishing stones after this.


    Once the back is set I move onto the front side.

    If you are careful, and only just flatten, is their a reason not to polish all the way through to polish stones? Or does it just not matter? Seems like an incomplete sharpening if you jump from 1K to 10K.

    If you want a 10k edge, you need to put the ura through your entire progression. Just keep track of the scratches and make sure they are the grit you want them to be.

    Yeah Bert you go through all of the stones to get to the polish stones.

    Jon is seeming to say just go to 1k, no polishing. Then when the front bevel is done de-burr the ura on a polish stone. Thats what I would do after flattening and going thru the progression on the ura. But for resharpening I wouldn't touch the ura except to de-burr the ura with a polish stone.

    That's correct.

    I always say just the high grit stone because i'd rather someone spend a lot of time on an 8k stone than mess it up on a 1k stone...if you are careful, then you can start with a lower grit stone. I always say what I say for the lowest common denominator (no offense meant...i just don't want someone starting out to mess up their knife because of something I said)

    I definitely appreciate you looking out for us (me) but if I had stayed with the 8k for the ura I was working on, I'd probably still be sitting here grinding that thing. As it is, it took a good 30 min of light grinding to get it half way decent and then blending it in along the entire length of the blade until it was pretty much flat again. It was so tedious, I could feel my last marbles leaving me, lol.

    As a member of the lowest common denominator club, I thank you.
