Unexpected tool for Macarons

I found this tool at a hardware store. I'm not a hardware person so I don't know what this tool is even called, but this gadget is certainly handy in the kitchen. I don't know its original function but I found this tool absolutely useful in removing macarons from a Silpat or parchment paper without damaging the macarons, especially when things get stickier and trickier ... I tried all sorts of spatulas and kitchen knives to remove those less than perfect, sticky-bottomed, macarons, at the expense of damaging my Silpat. Of course you don't necessarily need this tool for perfectly dry-bottomed macarons, but trust me, this tool is more useful that you might think.
