What The...? Wednesday

When I saw this in an antique mall last week, I was immediately drawn to the pretty blue metal and the green wooden handle. It has a super shabby industrial feel to it. I had no idea what it was until I read the tag, though. Thank goodness for sellers who know what they are selling, right? So, I ask you...do you know what this is? Leave your best guess in the comments- I'll be back with the correct answer tomorrow :)
