An iron rod with removable plastic balls holds several keys. The rod can be used as a lever to apply increased force.
Metal rod holds about 10 keys, while the wooden key holder only holds a maximum of 2 keys. Otherwise both work well.
Tip: Hang the key holder on a neck band with a long string to avoid dropping it.
