Nevron Stick
The Nevron stick was built years ago after tenth year at EH. Some of the Chosen felt Nevron was a bit tough. In "humor", Clalibus built a sword which Nevron would probably take a shot from if hit.
The Nevron Stick used Pole Vault core - the same kind usually used for Torch Poles. This leaves the core at easily 2" in diameter with about .5 left for MC1900 & MC1900S Foam.
Because the foam is dense, on casual inspection the stick passes for legal - until you hit yourself with it.
It is currently the only known weapon in Amtgard that has proven to derail the Night Train.
