>>422745 Flamethrowers are ridiculously cumbersome and not exactly suitable for using point blank, also tend to get you shot because people dislike being set on fire. In "close range" circumstances you'd want to use a knife rather than trying to carry about a flamethrower or sword.
>>423007 except that's not true: >No, it wasn't the actual trophy for the Korean Series champions. The Korea Baseball Organization (KBO) doesn't hand out swords or any form of replica weapons. >You see, the Dinos are owned by NCSOFT, one of South Korea's top game developers. The sword that was brought onto the mound at Gocheok Sky Dome in Seoul, after the Dinos' 4-2 victory over the Doosan Bears in Game 6, was the real-life replica of the "Execution Sword," a highly coveted item from "Lineage," one of NC's signature games.
>>424239 Don't know about laser swords, but some guys on youtube built themselves lightsaber lookalikes. One using a super heated tungsten (?) rod, and a much cooler one from a plasma torch which can extend/sheath at a button press and have different colors.
There are obvious usability concerns (you have to carry the gas canister) and it can only melt stuff, not deflect bullets or one-hit-kill space marines.
Chainsaws aren't useful in combat. Even beyond the impracticalities of wielding one they aren't actually that good at inflicting injury in the middle of a fight (you basically would have to continually press it against someone who can't move to saw away at them compared to a sword which slices/pierces through a foe effectively)
>>430537 Yeah, but one is a tool created to cut up static targets of great thickness, while the other is to wound soft targets. So this is normal. A blade doesn't cut on being pressed down flat on a surface either, except if you use the pointy top with great force. Blades cut on friction. You need slashing movements to cut, and even then you will be unable to cut thicker surfaces. Compared to that, chainsaws have the advantage of being constantly in movement, hence they provide friction merely on touch. So if you just push the flat part against something, it will cut them far more effectively than a blade, despite not being any sharp.
Now if you go Warhammer 40k and mount the chainsaw on a sword hilt, then you got a weapon that can not only wound by slashing, but also cut on pressure, and it is effective against the more extreme thick surfaces too.
