Cold Steel's VG1 San Mai III is not as chippy as Falkniven's laminated VG10 in my personal experience.
I had an A1, and that thing chipped like crazy. Perhaps I had a bad one, but I doubt it. Both Cold Steel's San Mai knives, and Falkniven's laminated VG10 knives are made by Hattori. Hattori is one of the very best knife makers, in terms of craftsmanship, on the planet.
I use a San Mai III Master Hunter as my go to hunting knife. Even through bone, I have never had a chip.
Also have a San Mai III Trail Master, and chopped extensively with it, as well as batoned. No chips at all.
The San Mai III Trail Master is convex ground also. I saw one for sale in the exchange, if you are interested.
VG1 as made in the Cold Steel version, is said to have more toughness than VG-10, but less edgeretention.
I believe them to be Great Knives!
Sorry to hear about Your experience with Your A1.
I don't know why there are differences in the user reports, but I think the knives should be the same for any owner!
I have used the A1 as my son has one.
His A1 doesn't show what You have experienced, so there are obviously differences between knives of the same model.
My son has accidentally hit a stone with the edge of his A1, but it dented instead of chipping.
I have done the same on Limestone with my NL2, but the denting was minimal and the edge was back after 5 minutes on the DC stone.
I have used the NL2 in chopping Sycomore Maple for 2,5 hours of continous work, without seeing any damage to the edge.
I have batoned & splitted firewood + chopped 4" to 5" Mapletrees, for years with the NL2 and it still have the original edge.
It only need maintenance from the strop and the ultrafine ceramic side of the brown DC 4 stone.
I'm happy for this and I'm content with the quality of that NL2.
It's the same with my NL1, even if I don't use it as much as the NL2.
IMO the NL's are what Peter Hjortberger, the owner of Fällkniven promise them to be.
He has personally told me many times, that to this date, he hasn't got any NL's back to him in pieces!
