    I have read several posts on this forum and other forums regarding different ways to remove wire edges and burrs. The method I am currently using employs edge-leading strokes with the 1.4 micron Micro Fine ceramic.

    The 1.4 micron is the last stone I use in my progression, and although some folks have suggested using a coarser stone for this task, I am following another suggestion that said that I should use the last stone in my sharpening progression.

    The edge-leading strokes that I have used so far to remove wire edges and burrs have been tip-to-heel, which should mean the scratch pattern that these strokes create should be somewhat parallel to the edge-trailing, heel-to-tip strokes I use in my sharpening progression.

    My questions are whether anyone has tried edge-trailing, heal-to-tip strokes in their sharpening progression, and then used edge-leading, heel-to-tip strokes when removing their wire edges and burrs?

    And whether this had any effect on their results?
    Thanks

    I suggest to you to finish each and every grit stone used in your sharpening succession with a few alternating side, edge leading strokes.  Do enough to completely and effectively address the entire length of the knife edge. By this I mean use a sharpening stroke that is pulled down and on to the edge with an alternating, left then right then left then right side stone strokes.  This will remove, or prevent, the formation of the wire edge with each every grit stone you use as you go through the sharpening process.  Then you won’t have the problem of a wire edge to deal with at the end.

    If your beginning edge trailing stroke was done heel to tip, the ending edge leading stroke done tip to heel should align your scratch pattern, in a parallel fashion, like your looking to do.

    Please exercise care when utilizing edge leading strokes.

    Thanks!  I will definitely try this approach.

    It makes perfect sense.  If I use good technique, I can see how I can have the apex angle and refinement that I want, and no wire edge.

    I’m pretty much in agreement with Marc.  Once I’ve created an apex, after each grit, I’ll use somewhere between 4 and 10 very light, alternating strokes to remove any burrs.   The primary reason is to inspect the edge, looking for a sharp apex and burrs reflect a lot of light and can look a lot like a dull edge.  You can waste a lot of effort trying to sharpen a burr.

    I only use edge-leading strokes when using stones below 800 grit.   For diamond stone grits above 600 grit, I will use scrubbing strokes to speed things up a bit, but normally I stick with edge-leading.  When I use diamond film, I use edge-trailing except for long, straight edges, where I may use scrubbing strokes.

     

    Correction:  Should read “I use only edge-leading strokes when using stones below 800 grit.”

    My 2 cents:

    I raise a full length burr at 100 grit, verify it with edge trailing finger swipe (obviously it is on one side only), I then do 1 edge leading swipe (consistently soft) along the full length on the side that the burr is curled to.

    Finger swipe again, no burr, move on. 25 strokes per side up thru diamond film and good to go. Every knife will cut scallops out of shiney magazine paper.

    The first step is the most important. If you do not have a distinctive burr that you can feel from tip to toe then you will not get the best out of your WEPS.

    I do this with resharpening also (may start with higher grit to preserve steel) because that flimsy plastic gauge works great for repeatability.

    Am I missing something that you guys are talking about ?
