Lithium (Li), Sodium (Na) and Potassium (K) all react with water, and can be cut by a knife. There is also Caesium, Rubidium and Francium that react with water (very very violently) however i do not know if these can be cut. They are the alkaline metals and make up group 1 on the periodic table of elements.

Don't forget about Lithium..
A lot of the first group elements are soft and react violently with water.

Sodium and potassium would fit that answer; both react violently with water.

Reaction with H2O leaves a lingering burned paraffin smell after wards
When placed in water it skirts around the surface with a fuzzing sound. Ask me we flushed some in the Lab and blew up the basin's plumbing just as the Science teacher came back into class

Potassium is also soft and reacts violently with water.

Sodium.
I once threw 1kg of sodium into a swimming-pool sized body of water just to get rid of it.
Spectacular wasn't the word to use!

Sodium. Because it reacts with water, sodium is usually stored in oil.
