I’m not trying to be snide at your expense when I suggest that if you have to ask this question you should probably do something else.

You don’t say what NLE software you use; your project will involve creating masks and key framing them as the blade moves. If you make the knife green and chroma key green the knife will disappear. That’s how chroma key works.

You can probably(?) create the effect by making a mask of the lava texture and imposing it over the knife. Every time the knife moves, however, you will need to adjust the position of the lava mask.

You might be able to do this in Photoshop or After Effects. I don’t know as I don’t use either of these programs.

You don’t say how you’re using this effect. Can you do a lock-down shot of the knife on a solid surface and then substitute the lava knife for the original? Done carefully you should be able to make a match-edit work here fairly convincingly or cover the exchange with an actor’s movement that blocks the view of the exchange.

Good luck.
