This appears to be a very effective weapon to 'take-down' a threatening Walking Dead
er within a 20' arc (or so), by means of a simple decapitation:
Jörg Sprave's Circular Saw Disc Slingshot
Sprave has built a slingshot that shoots circular saw blades down its path and they will fly a long way. The follow-up version has a top part that caused the blade to spin and stabilized the flight.

Only way to top that build of disc weapon would be to construct a 18 volt Lithium-Ion Laser Guided cordless weapon which ejects its disc along the path of its laser marker at full rotation speed, and which has a reloading magazine like a auto vinyl record-changer!
There's still a lot to do to change THIS into a deadly Laser-Aimed Rotary Saw Disc flinging weapon
. The stacked saw disc magazine (Saw Changer) in particular is going to require much . . . . input & effort!
Inspiration for the Reload Magazine
here! Its going be a "His Master's Multiple Zombie Head-remover
" when its completely finished!
