What causes chips in the edge of the edge? I know I have read this somewhere but can't figure it out? The last three knives I done, I have had a problem with chipping.
The definition of insanity is to do the same thing over and over again and expect a different result?

I would say that it could be a couple of things that can cause chipping.
One is that you sharpened the blade with coarse stone then never polished out the coarser scratches.
Two is that you have made too fine of an edge and in doing so the wire edge broke off and caused some chipping.
Three is you could have contaminated finer stones with grit from the coarser stones.
Four is you are too rough when working the stones. When the stone contacts the blade the slapping sounds could be what I mean.
Five is not having the stones flat on the blade when working them. Having the side edge of the stone contact blade first or when working the stones.
That is about all I can think of off the top of my head

Often it's using a coarse stone all the way to the edge, then not using the fine stones enough to smooth it out.

Sometimes it's leaving a burr or wire edge that feels rough or chipped.

Occasionally, it can be the steel (but probably not 3 knives in a row).

This has to be it! I was trying to see if I could practice for "20 knives a day" and was going at pretty fast pace!
So much for flying along? :S :huh:

Better answer... didn't see it... you must have posted while I was typing mine.

Glad we hit some of the same points. :)

Yes I was typing it at the came time. I posted it and looked up to see who else was on this thread and there were 3 of us and you were one of them.
Thanks for the compliment.
