Needle-Rapier

Needle-Rapier
Weapon (martial, rapier), common
The Needle-Rapier is the signature weapon of the Muridae (Mousefolk), particularly the Acorn Guard. These blades are forged from high-quality reclaimed steel and are honed to a point so fine they can pierce the smallest gaps in heavy plate armor or the thick carapaces of giant insects. Despite their name, they are durable enough to parry strikes from weapons twice their size.
