Quiet Edge

This unassuming blade produces no sound when drawn or swung. On a hit, the target takes an additional 1d6 damage. If you have advantage on the attack, this additional damage becomes 2d6 instead. When you score a critical hit with this weapon, you cast Silence (centered on the target, no concentration required) lasting until the end of your next turn. The affected creature cannot produce sound, and any spells requiring verbal components fail while within the effect.^[1]
