The new N-Force Klaw Hatchets released by Nerf are, as of yet, my personal favorite melee weapons: I recently saw these at a local Walmart for $ 7.99 USD and bought them. I now use them frequently, and when wielding two, they are very impressive against many other current N-Force weapons.
The Klaw Hatchet measures approximately 14.5 inches in length and weighs far less than what would be expected. The Hatchets are made with a new slightly less durable but far softer foam, making them easier to throw, and also can be used in close range melee combat while dealing minimal pain to the opposing player. The Klaw Hatchets are effective weapons, and for the very cheap price, I highly recommend them.
