This video randomly popped up in my feed. It goes into detail on burrs with accompanying photos - I found it quite interesting. They point out that removing a primary burr (the main big burr that forms) leaves behind a secondary burr, and then they go into a lot of detail on the types of secondary burrs and why they negatively affect sharpness.
At 5:45 they start talking about “negative” burrs, which they define as burrs that break off during honing vs forming a “secondary” burr (feather or wire edge) like “positive” burrs do. I believe the presenter/author uses powered systems so it’s not fully applicable to stone work, but there’s probably a decent amount of crossover.
I’d be interested in comments on how this aligns to people’s experience with the steels they categorize as forming positive vs negative burrs, if you’ve sharpened knives from both columns. I only have SG2 from the negative burr column, although I have a vtoku2 knife from the positive column coming soon.
