Throat depth is the entire reason these exist. A standard stapler reaches a few centimetres in from the edge, which is useless when the staple has to land on the fold line of an A4 sheet folded to A5. A long arm reaches the centre and saddle-stitches a booklet properly. Check the throat measurement against your largest sheet. See staplers, staples and binding supplies.
