Would be nice to hear Cliffy's take on this too.Zenith wrote:I agree with you. A while back I was adamant on creating a burr while sharpening and since then also try to create as little burr as possible.
I mean take a look at this image and the scale it is. I was wrong with my previous mention of 200um

At this stage, giving some thought to what I said previously I have to start asking if what we see at the edge might be carbides or such sticking out and not even be a burr?
If we take into consideration that carbides in O1 can be 0.7um (have a look at this link http://www.hypefreeblades.com/files/schneiden.pdf) at some point we will get carbides at the very apex.
I might be missing the pot completely with my interpretation, but would be willing to discuss.
