have you heard of a "Chinese Weeder"

I will start by saying that I am not sure that is the name of it. A friend of mine has this tool. I used it the other night to weed with and really took a liking to it. She said she thought it was called a chinese weeder. She also said she thought she had gotten it from a book called The Pinetree.

It is a hand held tool. Shaped sort of like a farm plow shoe only smaller of coarse. The handle is rather short and curved back kinda ontop the shoe part but, off to the side.

I've never seen one of them before and would sure appreciate any help that you might be able to give me.
If I am not able to find it ... I am gonna try to get a picture of it next time I am at my friends house.
Thank you in advance.
