Nasty weapons
The nasty weapons pack was released upon the Austrailian Christmas update. This pack includes the boston basher, a melee weapon for the scout that appears to be a bat with nails in it and has a curved handle. The pros of this weapon are, it causes a 5-second bleed on the enemy upon succesful hit, but if you miss, you inflict damage upon yourself and bleed for 5-seconds. Next, The Backscratcher, a melee weapon for the pyro appears to be a hoe or rake of some kind with blood splattered on it. It does less damage then the fire axe but upon successful kill, you receive a small medi-kit. Next, the fists of steel is a melee weapon for the heavy, appears to be gloves or gaunlets made completely of some metal ( probably steel ). The fists do 60% more damage and receive 100% more damage from melee sources.
