Spearhead fluorescent tubes

Name: Spearheaded fluorescent tubes
Description: fluorescent tubes that are fitted with spearheads
Special abilities: The spearheads are made of a durable carbon steel alloy, which with the correctly provided momentum/force, can penetrate any surface, nor can they be easily dug out. These fluorescent sticks are usually 15cm in length, though varieties with a length of 1 or even 2 metres can be prepared; These can be filled with any substance or chemicals due to a durable chemical and heat resistant transparent fibre material (similiar to bulletproof glass but less dense) that is used to construct the 'glass' component of the tube's body. These can be either launched by any projectile launcher (excluding firearms) or can be thrown or used as close quarter combat weapons, though their use in close quarters are severely limited, and are effective for one thrust per tube.

So essentially a spear that can be filled with something and breaks on contact?

not necessarily breaks; it probably will break if used as a CQC weapon if used to stab more than 2 times, but when fired/thrown to stab at someone, there is enough force to make sure it penetrates the target, but does not break. So basically, it does not break unless used to stab more than once.

Just a pet peeve at this point, but I would rename this. Fluorescent tubing is about as sturdy as tissue paper and doesn't exist in One Piece. I'm not exactly what you would make them out of to withstand more than one hit unless it's just a thin metal, but I'll leave that to you.

Sorry for taking so long on this.

hmm.........ok, how about this? I make them usable for one hit/throw; the reason they are glass tubes are because i am basing them off test tubes; simply put, they are combat ready containers of various substances. They also could act as a light source.

Then one of the substances inside could just be something luminescent, like a glow stick. If the chemicals for that are unavailable in One Piece, then bio-luminescence works as well. It probably doesn't help that the technology for bulletproof glass does not exist in this setting.

ah, then it doesn't need to be bullet proof then; one hit and the tube breaks. I'd just like a transparent apparatus for chemicals. Is this acceptable?

yup
