    3-5mm off the stone for a Global is pretty extreme, in my book!

    Yeah that's what I thought when it happened. Tho 3mm off any knife without a visible defect is pretty extreme in any case.

    Global steel is so gummy and tough, that I am very surprised it could even chip like that...especially on a 5K stone?

    I sharpen a G-2 that my girlfriend uses with less than a 20 degree angle, and there have been no problems at all (and she goes hard with it). So your issue doesn't seem common in my experience.

    Hmm maybe it was just a bad shipment?

    Globals are also among the most counterfeited...

    I didn't know that... How do you tell if it is a real global?

    Carbides are not that big. Large carbides break off in larger clusters than finer grained steel, and you can feel it, but you need some magnification to see any difference.

    Did you see it break? And did it break off in one piece that you found? How fast were you moving?

    I ask because it's possible that you were abrading the knife against an edge of the stone due to improper pressure and/or dishing and actually ground the "chips" into the blade without noticing.

    Yup I saw it break. The way I was sharpening was the way it was shown in Jon's vidoes. I was not moving fast at all by any standards, in fact I was moving slower then Jon did in his vids cause I'm still kinda getting a feel for it. The stones were pretty flat so i don't think dishing was an issue. The break actually occured when I ran my fingers across the blade like that:
    I was doing that when a piece came off in my fingers...
