Make a magic wand and a one-handed dagger into a second-hand weapon

I would like to see wands and one-handed daggers as second-hand weapons like a shield and bow. There is almost nothing to occupy the other hand in this game. But a rod and a dagger would be very suitable for this role. This would diversify the build process and make it possible for those who do not need a shield or bow to build with their one-handed weapons to use a second hand.
