A weapon wielded by various NPCs and enemies in Hollow Knight: Silksong.
A pin is a very slender Weapon, akin to a Rapier. The handle either has (more commonly) a rounded hook in the shape of a broken ring or letter "C" at the end, or (less commonly) a handguard forming a "D" shape.
Do not confuse pins with Hornet (Hollow Knight)'s Needle (Hollow Knight): the latter has a complete, unbroken circular ring at the end and the blade widens significantly before tapering to a point.
