Switchblade (Fallout 4)

The switchblade is a melee weapon

Gameplay
The switchblade is a small melee weapon that may be swung fast, but with small damage inflicted upon enemies. It is first thrust at an enemy before swinging it in a slash with the second swing. With one investment in the Blacksmith perk, the serrated blade nearly doubles the switchblade's damage and adds bleeding damage.
