Needle

Needles are one of the most common weapons in the tower, but also one of the best. They are thin spikes, generally used to pierce and stab. An example of a very powerful needle is the Black March, although it has been made clear it is not the strongest needle.

One reason the needle is the most basic weapon in the tower is that piercing and thrusting attacks receive less shinsoo resistance, and are technically more aerodynamic. A sword that requires a swing will have to break through more shinsoo due to having a greater surface. Piercing versus swinging could be compared to dropping a scrunched ball of paper versus dropping a flat sheet.
