Instead of just talking stats, why don't we ask ourselves what function this weapon would have alongside Medic's other melee options?

Most of medic's melee options are more about utility then damage, despite often being his go-to panic option. What if this saw could fill that emergency damage niche?

Alternatively the weapon could go for a "I'm taking you with me" deterrent approach, killing attackers posthumously using bleed or debuffs.
