This shard of ice is long and slender, roughly the size of a dagger. The ise (ice) rune glows within it. The shard has the following properties, which work only while it's on your person.
Frigid Touch
As an action, you can touch a body of water and freeze the water in a 10-foot-radius sphere around the spot you touched. Once you use this property, you can't use it again until you finish a short or long rest.
Frost Friend
You have resistance to fire damage.
Icy Mantle
As an action, you can touch yourself or another creature with water on your finger. The water creates an icy mantle of protection. The next time within the next minute that the target takes bludgeoning, slashing, or piercing damage, that damage is reduced to 0, and the mantle is destroyed. Once you use this property, you can't use it again until you finish a short or long rest.
Winters Howl
As an action, you can cast sleet storm (spell save DC 17). You regain this ability after you finish a short or long rest.

The transfer takes 8 hours of work that requires the two items to be within 5 feet of each other.
