I want to know the cross of a tool?

I've seen a tool on a diy program and want one, but I don't know what it is.

It be a criss cross of thin metal which you'd verbs open to all along the job, and it would clearly devide the living into points.

Answers: i know what you mean, i assume its called a pantograph or something similar
