    Probably the most "ghetto" way to do it would be to mask out an oblong shape in a black plane, feather the mask, and then blend it (multiply/add) into the footage.  But that would most likely look really ugly.  Another option is to Photoshop the burn mark in its entirety and then gradually un-mask it as the blade burns along its path.

    Anyone else have any other, better ideas?

    Maybe this can help. A tutorial from RodyPolis.

    That Rody tutorial is a great method, but requires the particle add-on for HF3E or Hitfilm Pro.

    Very true. I thought I would add it to the database of knowledge for anyone who ever searches the forum.

    Is there any solutions that does not require add on pack?

    Yeah, SteveKarstensen pretty much hit it. You'll have to either draw the burn using Hitfilm effects and masking tools or import a photo of a similar element (Scoring some dirt with a stick, taking a photo and bringing that into Hitfilm to mask and color correct would work). Then it's a matter of keying/masking the burn and placing it where needed, again, using masks to reveal. Tracking might be needed for a moving camera shot and roto for anything crossing in front of the burn.

    You'll actually want multiple burn elements--the dark one for the scortch and an copy of basically the same burn, but brightened up with glows added for the initial heat. This overlay layer will also have to be keyframed to reveal and fade.

    For sparks--well, without particles there's not great ways to create sparks in HF3E, so you'll need to look for stock footage (maybe some greenscreen stock on youtube https://www.google.com/search?q=yourtube+greenscreen+sparks&ie=utf-8&oe=utf-8#q=youtube+green+screen+sparks )
