There are different kinds of knowledge, and according to your comment that "wisdom is applied knowledge," I infer that your definition of knowledge might be
Information that is not yet applied to a situation (for example).
If I'm correct, then I think you're on the right track. Knowledge IS information, and when it comes to spiritual gifts, God is able to give information to the possessor of this gift either prior to the information becoming a fact or at the very moment the word of knowledge is given.
The Gift of Knowledge
The gift of knowledge might be revealed, for example, when a believer tells another believer,
"God is going to heal you of _____________."
You can fill in the blank, above, with the word cancer, or diabetes, or panic attacks, or whatever infirmity you care to name. The imparter of this utterance could be thousands of miles away from a given situation--one in which a missionary who is in danger of being kidnapped by terrorists, for example. During a time of prayer, the person with the gift of knowledge says to himself, "God is going to prevent missionary Jones from being kidnapped."
If the gift is genuine, not only will missionary Jones not be kidnapped, but the person who uttered that knowledge might have the joy of telling that missionary the "good news" a day (or a week, or a year!) later, and the missionary may (though not necessarily) recount to the glory of God how the deliverance came about!
To be sure, there is wisdom involved in the speaking of knowledge, but that wisdom originates in God, and the speaker of that word of knowledge is but a channel for a supernatural, God-imparted word of knowledge. The "test" for whether this gift is legitimate, of course, is if the word of knowledge turns out to be true! (At this point, I will not dare to venture into how this gift can be perverted whenever Satan seeks to insert his counterfeit word of knowledge into a situation, though I'm sure it does happen on occasion. I will suggest, however, that a person with the gift of wisdom could potentially discern such a satanic counterfeit and expose it for what it is.)
The Word of Wisdom
Now to the word, or utterance, of wisdom. The speaker of wisdom can look at a situation which already exists--say, for example, whether or not a local assembly of Christians should seek to plant a sister church, and takes the knowledge he or she has gleaned from God's revealed will and word in the Bible, and applies it to the situation at hand.
If all goes well, the congregation heeds that word of wisdom and it is confirmed by a unanimity among the entire congregation. Situations are at times far from ideal, however. In other words, wisdom imparted is not always wisdom applied!
In conclusion, whether we're talking about the utterance of knowledge or of wisdom, the source and imparter of the gift is God's Holy Spirit. We His children who are privileged to be indwelt by His Spirit are merely the recipients of His gifts. Moreover, we can also be filled with His Holy Spirit, and when communicating His will and word we are but God's mouthpieces, much like the prophets of old.
"For to one is given through the Spirit the utterance of wisdom, and to another the utterance of knowledge according to the same Spirit . . .. [Both] these are empowered by one and the same Spirit, who apportions to each one individually as he wills."
