Question about magic item

[Klaatu_the_druid]

The Rapier Frost Brand: "When you hit with an attack using this magic sword, the target takes an extra 1d6 cold damage. In addition, while you hold the sword, you have resistance to fire damage."
Do you get the fire resistance simply by holding it in inventory or does it mean you get it when wielding the weapon? I think of Bag of Holding for instance and means inventory. Thanks for any guidance on this!

[Zacchaeus]

It says while you hold this weapon - so having it in your inventory isn't sufficient. You'd need to actually be holding it in your hand.

Ypep, has to be held in one of your two hands. You could attack wit a weapon in a different hand, but being in inventory is certainly not enough.

Thanks for both responses - yes, makes sense you have to be holding it, just wanted to double check.
