How well would that work for you? Remember you have to use your icon as a survival tool in both fighting and eating. How do you manage?
Also be sure to mention what level you are in your post, so when you advance to a higher level, if you ever do, your post won't seem nonsensical.
Me with my current level 26 switch blade, I'm pretty much screwed for fighting. Not only is this an extremely short ranged weapon but switch blades are small all the way around and could not inflict much damage to a zombie. The best I could do would be to cut their jugular mains which in and of itself is a terrible idea with a short ranged weapon because I'd be essentially sticking my fist into it's mouth. Not only that, but zombies have incredibly low blood pressure, so trying to kill it that way is pointless being that it essentially wouldn't work. I really would have been better off with the level 23 fire ax.
Now as a tool for food, this is significantly better. Should I ever run into a can that doesn't have it's own opener, which I would imagine would have to be very old, I could just stab it open. Of course this would have to be after I washed it in... Oh I dunno, acid, to rid myself any chance of catching the virus before I use it as a tool for food.
