I watched YouTube video about the ionic bonds in cutting mediums...
Yeah, chemistry/physics is the only way to go in describing what's going on here. Basic geometry just doesn't cut it. Pun intended.

Well, I did enjoy the thread, there is ton of information in those posts...Yeah, chemistry/physics is the only way to go in describing what's going on here. Basic geometry just doesn't cut it. Pun intended.
I personally like convexed blades,
I own few and I find that they cut different mediums differently, compared to full flat grind for example, I cannot argue with this, I guess medium matters.
This is the picture, besides all other, that grabbed my attention the most:
It represents plane, chisel grind cross section, but if you draw a line between the tip of the un-used blade and the tip of the 800lf worn blade, than mirror the 800lf worn part and stretch it to the 0 worn blade point, you'll have a convex grind, isn't it ?
So I'm thinking, convex grind may not be the "sharpest" grind, the grind that will "bite" as full flat grind, but it will give you in average better wear resistance (plus of course all the other factors that are playing role in this as type of steel, hardening, "angle" and so on, if compared in same medium, under same conditions, with another grind...
I found my convex blades to take very sharp edge and after being used, I can bring them back to razor sharp edge with few strops only. For chopping woods, splitting and so on, they are outstanding, on a wide enough edge where the inclusive angle is small, they are excellent meat slicers too...
