The Last Of Us – Crafted Tools (Melee Upgrade, Shiv, Health Kits)

While most of the time Ellie and Joel are scavenging whatever they can find to use there are cases where these items can be combined to makes something better. These are your Crafted Tools and they can be a very big thing to have in any number of circumstances.  Each of these Crafted Tools has 2 upgrades for it.
