We have two common screws which are cross and slot, but we usually don't have both two kinds of screwdrivers when we need them.
"Cross and slot" provides both the cross and slot screw drive in just one screwdriver, and you can switch them very quickly. One screwdriver will be sufficient to meet the daily needs of locking screws and reduce waste of time for looking around for proper tools.
