Arcane Blades

This special design of Bladed Knuckle Dusters have sharp zigzag-shapes for each knuckle, giving them spiked "teeth". This is coupled with a single-edged blade at the end of the Knuckle Duster. Arcane Blades are edged-weapons forged out of a special kind of metal that is capable of absorbing magical energy and can be used as a spellcasting focus

This weapon deals 1d4 Piercing or Slashing damage, the choice must be made during the attack.

Arcane Focus - While wielding an Arcane Blade, a magic user can channel magic into it. You may add your Spellcasting modifier to the weapon's damage, and you can spend a bonus action to change it's damage type to that of a spell you can cast, until you choose a new damage type. By expending a spell slot, you can add the damage and change the type of damage to that from a spell from your spell list as if you had cast the spell so long as the attack hits.

Proficiency with a Dagger allows you to add your proficiency bonus to the attack roll for any attack you make with it.
