Banging steel to attract attention

Something i would like to see is to be able to clang your sword (if zerk) to attract Zeds.



ie: Demo has FP bearing down, Zerk can clang against steel to attract it if they are within like 5 mtrs.



would be a zerk speciality, but others can do it to a lesser degree with a knife.



Also, probably been mentioned, Rifle but head crunching.
