** There's also Shura from the same arc who uses a Heat Javelin, a JoustingLance with a Heat Dial inside it that lets him stab and burn things simultaneously.

* Actually not a good idea in real life, even if it were feasible; as any blacksmith or metalworker can attest, steel loses its hardness the closer it gets to its melting point. It'd take some very special metallurgy for the material to both glow white-hot ''and'' still be viable as a hard cutting edge.
** [[https://www.crucible.com/eselector/general/generalpart4.html Such special metallurgy has existed since the 1930s or so]] with "high speed steels" - which were developed in response to modern industrialized machinery (like drills, end mills, ect.) becoming more capable and having higher RPMs. So, instead of finding roundabout solutions to the problem of drill bits heating up and dulling because of it, high speed steels were developed which simply retain their regular hardness at high temperatures with addition of molybdenum, tungsten and cobalt. With some of these steel alloys, ''operating'' temperatures in excess of 500°C (almost a thousand degrees Fahrenheit) are possible. More if you're willing to sacrifice some hardness. To make things even better for potential application of this, high-speed steels are popular in high-end cutlery and knife making. Steels like CPM M4 are becoming extremely popular because of how "hard" the steel can be ran (usually well above 60 HRC, which is about where most steels start to top out at before becoming too brittle - some alloys can almost reach 70 HRC, which is nearly on par with the higher end of ZDP-189) and it's wear resistance. Steels like CPM M4 and CPM Rex T15, especially, on a properly forged knife would seem like space voodoo magic to someone unaware that such capabilities were possible. Heating one up, however dangerous and unwise that would be to use, is certainly possible.
** [[https://www.youtube.com/watch?v=hjSheQ7LgJ4 As this experiment tells]], while a RealLife HotBlade may ''look'' impressive in some stunt, cutting power is not much increased, even with incandescent 1000°F knife.
* There once was a practice called "Blood Tempering," in which a red-hot blade is inserted by stab-wound and/or anally into a slave or prisoner of war, as it would cool the sword at body-temperature. This supposedly made the blades much stronger, and always killed the stab victim in practice.
** Almost never used, actually. And because the human body has such a wide variety of liquids and materials, it invariably created a blade with a poor, uneven temper that shattered easily. The practice was almost never maintained for any length of time in any culture, despite a moderately common myth.

This is because the human body has such a wide variety of liquids and materials, it invariably created a blade with a poor, uneven temper that shattered easily. The practice It was almost never rarely maintained for any length of time in any culture, despite a moderately common myth.

* Many Warhammer swords (at least in the way they are visually depicted), both ''WarhammerFantasy'' (Archaon) and ''TabletopGame/{{Warhammer 40000}}'' ('''THE GOD-EMPEROR OF MANKIND'''), even when some flames might flicker depending on the artist, verging into FlamingSword territory.

* In ''VideoGame/YandereSimulator'', Yandere-chan has the option to heat up a knife blade with blowtorches. As of right now the effect is more cosmetic than of practical use...unless you want to turn it into a FlamingSword instead.

* [[VideoGame/RocketKnightAdventures Sparkster the Rocket Knight]] sheathes his sword ''in'' his jetpack, and several of his stronger attackers have his sword glowing with a blue, orange, or red flare indicating that he traps the heat in his sword. One of the powerups he can find in ''RKA 2'' upgrades him outright to a FlamingSword.

* In December 2016, YouTube began heavily promoting uploads featuring red-hot knives slicing through things. Those are fine in their place, and they no doubt have their fans, but many users have reported them [[AdoredByTheNetwork cropping up quite regularly in the Recommended list]] despite consistently clicking "Not interested" every single time, even amid an entire list of unrelated content. It's [[MemeticMutation become a meme]] for some reason, though it's hard to tell whether that's because YouTube's been pushing them so much leading to a sarcastic reaction in the form of a meme or if it really did take off that well. [[OlderThanTheyThink It's not even a new concept,]] as things like "red hot nickel ball" long preceded this new "craze" and remain a popular niche of their own.

* ''FanFic/XCOMRWBYWithin'' has Blake carrying a knife with a low-power laser in the handle, which heats the blade and allows it to more effectively penetrate armor and hardened skin. [[note]] Blake is the only one stated to have one, since XCOM operatives, with the exception of [[HollywoodCyborg MEC]] [[RocketPunch Troopers]], do not carry melee weapons. She specifically asked [[TheEngineer Dr.Shen]] if he could make something for her to use as a last resort.[[/note]]
