You call that breaking pretty easy? I'm amazed at what it stood up too for a knife as small as it is. I have one, and it's not at all large, or thick. It does chop and cut well, but hitting it on the side with a 2X4 is attacking it at it's weakest point. This is not what you would be doing if you chopped or cut, or even batoned with it.
This video didn't in the least make me nervous about using mine hard, or recommending it to others.
3V is an excellent steel that takes an excellent edge easier than most stainless steels. It likewise has more wear resistance than traditional high impact carbon/alloy steels like 5160, L6, S1 S7, A2, etc.
