Barbed Wire

As the new high insternal walls got added and that the wooden one had barbed wire at top, i tough maby u can like craft barbed wire and place it on the stone walls. This wire needs of course some HP like 50 like the spike floors but can only be braked with an sharp weapon like a sword, cuz how does it make sense to brake barbed wire with an pick axe easy? I would jsut like to see this in the game just cuz it could make alot more use of the stone walls.
