Powerjack

The Powerjack is a pyro melee weapon that can be found in shops from the beginning of the game on, and in other non-chest sources beginning on the second forest level. It has the same stats as a shovel or bottle, but it gives the player a speed bonus of 50, enough to make a pyro or soldier faster than a scout.

Strategy
Mandarbmax says: This is one of the best weapons in the game, add a precision add on for range, a health leach addon for damage (and healing) and a haste addon for attack speed and it can hold its own against an eyelander, but with a massive speed boost too!
