Template:List of weapons without random but with situational crits

List of weapons unable to deal random crits but able to deal situational crits
Soldier	Primary			Deals critical hits when reflected by a crit-boosted flamethrower.
		Cow Mangler 5000
	Melee			Deals critical damage while the Soldier wielding it is rocket jumping.
		Market Gardener
Pyro	Primary			Guaranteed to crit from behind.
		Backburner
				Gradually fills a "Mmmph" meter as fire damage is done, allowing a Pyro to begin a guaranteed 10-second crit period when full. This boost only affects the Phlogistinator.
		Phlogistinator
	Secondary			Accrues a critical hit each time it is used to extinguish a teammate.
		Manmelter
	Melee			Deals a critical hit when striking a victim who is on fire.
		Axtinguisher†	Postal Pummeler
				Сrits against wet enemies. This includes those who are in or have recently emerged from a source of water, and those coated in Jarate or Mad Milk.
		Neon Annihilator
Engineer	Primary			Accrues 2 Revenge Crits for every kill and 1 for every assist made by the user's Sentry Gun once the Sentry is destroyed.
		Frontier Justice†
	Melee			Will perform a critical punch on a third successful consecutive punch, causing a different kill icon.
		Gunslinger
Sniper	Primary			Automatically score critical hits on successful headshots. Rifles can only perform headshot crits while scoped (except for the Classic, which instead only performs headshot crits when fully charged).
		Sniper Rifle†	AWPer Hand
		Machina	Shooting Star
		Bazaar Bargain	Hitman's Heatmaker
		Huntsman†	Fortified Compound
		Classic
	Melee			Will critical hit at any time it would normally mini-crit.
		Bushwacka
Spy	Primary			Automatically scores critical hits on successful headshots. Only when at full accuracy. The damage of critical hits scales on distance fall-off from 102 to 51. Any shots further than 1200 hammer units will deal only base damage.
		Ambassador†
				Stores one critical hit for every successful backstab and every building destroyed with the user's Sapper attached.
		Diamondback
	Melee			The Spy's melee weapons always and only crit on backstabs, boosting the damage of a backstab from 2x the victim's current health to 6x. Knives can still be forced to crit, but this will only result in triple the melee damage, not backstab damage.
		Knife†	Saxxy
		Sharp Dresser	Black Rose
		Golden Frying Pan	Prinny Machete
		Your Eternal Reward	Wanga Prick
		Conniver's Kunai	Big Earner
		Spy-cicle†
Notes		†Includes Festive, Australium, Botkiller and Decorated variants.
