I just finished this one yesterday.
The handle is cut from a white oak crook and the shank is a bit of a rarity around here. A piece of dead alder. Usually by the time a piece of alder hits the ground around here it's pretty well mush. I can only guess why this one isn't rotten.
Either way, instead of turning to unusable mush it developed some really nice color and texture instead.
Here's some pictures.
