Sinister Looking Letter Opener (5e Equipment)

Weapon (dagger), common (minor)

This magic dagger has a fiendish-looking blade and is used to open letters and documents without being noticed. When you open a letter or envelope or break a wax seal, you can use the same letter to close the document or repair the broken seal within the next minute.

In addition, when you cause damage to a creature using this dagger, you don't draw blood from the victim, and the wound instantly closes behind it, leaving no traces or scars, making it a perfect tool for killing without leaving a trace.
