Bacon?

So you’re waving around a long four-foot length of metal with a grip that just *might* be wrapped in a thin layer of leather mostly to prevent slippage if your palm gets sweaty. Then due to a magical enchantment, the aforementioned big chunk o’ metal just starts on fire.

That just raises questions.

If the sword is cauterizing the wounds it inflicts, is it less effective than a non-flaming sword? Do you need to get a special sheathe for a flaming sword? Is it still hot after you turn it off? What if the wind is blowing towards you? Can you parry effectively with a flaming sword or is the blade softer? If the entire blade is fire, can it parry at all?

I can think of less scary cursed swords.
