Hat Circumference Measuring Tool / Scissor Type

[Mr.Habanos]

Hello, I am pretty new here and still trying to navigate around this site, so forgive me if this post appears more than once.

Does anybody know what the proper name of a scissor type hat circumference measuring tool is called? I've seen one and I'd like to get one, but can't find them anywhere.

Thanks in advance,

Mr.Habanos
