Quick Recommendation: The Bat and the Holy Mackerel are solid, but he Candy Cane has a nice bonus.

The Bat
Known by the loud ‘ping’ it makes as it connects with an enemies skull, the Bat is still a solid choice.

Sandman
The Sandman does the same damage as the bat, and can also launch a baseball at enemies that stuns them on contact, but lowers your max health by 15 when carried. After several updates that reduced the stun power, it’s now hard to get enough use out of the sandman to justify the health penalty. The sandman also give the scout a kill taunt. Can be gained from achievements, and purchased for $0.99.

The Holy Makerel
The cosmetic upgrade to the Bat, the Holy mackerel also announces every successful hit on players. Can be crafted by combining a Sandman with Reclaimed Metal, or purchased for $4.99

The Candy Cane
When carrying the Candy Cane, a small health pack is dropped every time you get a kill, no mater if you used a gun or the Candy Cane to get the kill. Extremely handing for topping up health and putting out fires, but causes you to be 25% more vulnerable to explosive damage. Watch out for soldiers! Can be crafted from a Kritzkrieg and a Pain Train, or purchased for $2.49.

The Boston Basher
A high risk/reward weapon. On hit you do the same damages as you would with the bat, AND the enemy bleeds for 5 seconds. But if you miss, you hit yourself. Good for sneak attacks. In my mind, it will help you kill noobs/newbs even quicker, but be a disadvantage when fighting skilled players. Combine a Sandman and a Tribalman’s Shiv to get one, or purchase for $2.49

Sun-On-A-Stick
The Stun-On-A-Stick is unique as one of the first promotional items that you will also be able to get from crafting. Besides looking awesome, the SoS doesn’t have much going for it. You get a damage bonus vs players who are already on fire, but 5 less base damage vs all others.
