I see where Arrowdynamic Solutions is coming out with a broadhead that is made out of "Flexible Nitinol Razor Wire blades". Supposedly it will bend or compress around obstructions and "spring" back "to cut more".

They have dubbed the name of the broadhead "The Atom".

The "wire" or blade is shaped similar to the orbit of atoms we see in illustrations and is somehow connected to a one-piece ferrule that has a cone shaped tip.
