In [the previous post](https://worldbuilding.stackexchange.com/questions/158871), I asked what would happen if armour outpaced modern firearms.  The answers I received are all very interesting.  There is one point that comes up however that I never considered.  And that was that there would the distinct possibility that melee would return in the form of maxes and war hammers.  But knights also used rondel daggers to go through weak points like joints and half sword technique to allow the point to go through the visor.

So what I’m saying asking is; Can a Mono molecular point go through the weak points of advanced carbon armour like the joints?  And considering that this mono molecular technology, can it cut as well?

EDIT: the blade itself is a steel blade that has advanced carbon materials in the crystalline matrix in order for it to hold a mono-edge
