This should be called a "hand made spine piercing before sewing frame" but for ease we call this a hole punch frame, which is hand made in MDF or similar wood and is an excellent way to pierce holes into the spine of the paper before sewing. Holes can be pierced in equal dimensions along the folded edge by using a bodkin or similar equipment. This lightweight frame measures 6" tall by 14" across and will be large enough to prepare most single sections. Comes highly recommended.
