To sign *knife*, form both hands into '1' handshapes with your index fingers extended and your other fingers curled into your palms. Hold your non-dominant index finger out in front of you, pointing diagonally across your body. Then, bring your dominant index finger down and brush it off the side of your non-dominant index finger. The motion looks just like you are whittling a piece of wood.
Sign *knife* using the whittling motion with your index fingers, followed by the signs for *cut* and *apple*.
Point to the object or sign *knife*, then use the sign for *sharp* by flicking your dominant middle finger off the back of your non-dominant hand.
Sign *butter* by wiping two fingers on your non-dominant palm, followed by *knife*, and then use the *where* sign while furrowing your eyebrows.

Yes! Your dominant hand should always be the one doing the moving, acting as the knife blade. Your non-dominant hand stays completely still and acts as the base or the 'wood' being whittled.
They are related but different. *Knife* specifically uses the '1' handshapes brushing against each other. *Cut* often uses a 'V' handshape (like scissors) or a different slicing motion depending on exactly what object is being cut.
For the noun *knife*, the dominant finger is typically brushed twice in a quick, short motion. If you are describing the verb action of slicing or whittling, you might use a single, longer, and more exaggerated movement.
