Chinese Polearms and Spades

[Paliandro]

Now, I don't know how much these relate to Kung-Fu, but can anyone help me recognize the long handled-wavy bladed sword kind of a weapon, and the spears with two squiggly bits to the sides. What are they called?
Also, I had understood that the monk's spade was the two-headed polearm with a crescent and a shovel, though I've never seen a antique one. I found online an antique chinese spear/polearm head named a monk's spade, which is crescent in shape. Were blades like that affixed to staves for use? Are this type of blades still called monk's spades?

Edit: I've also heard of some sort of shaolin rakes, but haven't seen anything that would look anykind of sensible. Anyone know about these?
