Invisible blade (dagger)

An invisible blade was a magically enchanted dagger that appeared as only a hilt, with an all-but invisible blade. Although it struck as a regular weapon, it was easily concealable, always silent when it struck, and never reflected light. Only the wielder of the dagger could see the weapon's blade, as if they were using the spell detect invisibility.

Creation
To craft an invisible blade, the spells invisibility, detect invisibility, gaze reflection, and a form of magical silence were used on the dagger as it was being forged.
