I have seen this exact same conversation on Facebook and other forums.
My 911 has chopped, battoned, been thrown and much more and it factory sharp over 2 years later. I haven't used my 1311 set but I need to. I don't think the SR101 performs the same as the old yard SR77 or infi. Also I think the convex edge seems to be the ticket for tough work.
I get better edge toughness out of SR77 vs SR101. I am sure that I have seen tests that report that also. I seem to remember seeing something about brittle edges chipping and then improving after repeated sharpening. That said, I prefer SR101 for the ability to take and hold a slicing edge.
I haven't seen any chips but on the simple carbon steel machetes that I use often, the chip doesn't seem to affect performance at all.
