    tiny slivers of metal falling off a freshly sharpened edge

    after sharpening 3 different carbon gyutos today i noticed a decent amount of metal slivers still hanging on to the edge. i deburred on the stones and used a cork screw to remove them, but im curious why this might be happening. is it something in my technique that needs work? or do i need to spend more time on a low grit stone? is this what people mean by "wired edge"?

    I've noticed this too. I always thought it was the burr breaking off unevenly on the stones. I'd like to hear some input as well.

    its just residual burr... if you have that after you're done, you may need to spend more time cleaning up the edge. This can be done on stones, strops, felt, cork, whatever... heck, i even use the back of a sponge sometimes.

    yep. i was dissappointed with my edges today, also. i raised much larger burrs than usual so that must be it.

    i figured that was normal part of sharpening? i always get those strips when i do a full progression.

    I don't know how I feel about this. Deburring on the stones means making smaller burrs to replace the big ones. And a cork screw? do you mean a cork? In my experience I have never been able to remove burrs effectively with cork.

    i dont know why i said cork screw. stropping on a stone works just fine to remove the slivers of steel anyhow, as they are barely hanging on to edge.

    FWIW I wasn't removing burrs with cork, but rather the residual slivers.

    not really, if done correctly.

    Unless someone has extreme luck in abrading through burrs, stones will always leave a burr. Most people just don't notice because they are invisible.
