The zombie uprising isn't for a few months, but lots have people have been getting prepared early! This one man Mr. Hickok45 has apparently combined zombie preparedness with Halloween festivity and now uses this to carve his pumpkins!
This man has videos going back to 2009 of this method, and has released one for this years season!
It does have the bonus of carving both sides at the same time! Though the face is a little :- | it would be a very quick method for some last minute pumpkins during an assault of the undead!
