help! what is this tool?

well, actually, i know what the tool is

it's a paper punch

my question is, how in the heck am i supposed to use it?

do i put a sheet of paper on a cutting board and whack this paper punch on it? Or whack the paper punch with a mallet, while pressing down on the sheet of paper?

why do i buy tools that don't come with instructions again?

ah yeah, cause tools rule!

interchangeable end pieces

with hand, for scale
