No You

Prerequisite: Must be wielding a knife in either hand.

If you have a dagger in either hand and you are targeted by a weapon attack that does not have the heavy attribute, as a reaction call 1 or 2 and roll a 1d2, if it is the correct number all damage is reduced to 0, also if this is a successful against a range attack, you may deflect the attack back by rolling to hit with half your proficiency bonus, if not you take the regularly applied damage. If the weapon has the heavy attribute instead of a 1d2 you must roll a 1d4.

This feat does not work against magic.
