@MrChewyWrites It's a tool used for drawing. It basically looks like a ruler connected to each other with joints, and pantograph is used for manually copying a drawing from a paper.(I remember way back in 2012, someone was selling pantograph and I wasn't interested from buying that one. And only for me to realize the pantograph can be useful when I'm suddenly become interested on drawing things. I regretted not buying that pantograph in that day)
