"The instruction below will allow you to heat up the blade of a machete to a temperature so high you will be able to cut through the flesh of the walking dead like butter. I advise you to be cautious while using - it can cause serious burns."
This mod changes the in-game appearance of all Machetes to the same. Even Kukris have the same model, despite being very different when unmodded.
This mod (unlike all other Fire Effect mods), won't light zombies on fire upon a critical hit, it instead deals the same amount of damage the critical hit itself did, as fire damage. Meaning that critical hits will deal double damage.
It does, however, always ignite poisoned zombies. Throw the 'plaguebearer' weapon at an enemy and follow up with a Hot Rod Machete (while they're puking) for an easy kill on Thugs, Rams, Butchers and even the final boss.
