maybe it could have a weak chain lightning on backstab or something

just spitballing

-dose max 250 dmg ( unless you buy damage upgrades in mvm)
-stuns target after doing the 250 dmage
-oly stuns if the target that is backstabed survives

what type of stun would it do? like a bonk?

Just a reskin

Here are my stats!

= The weapons attack speed will increase as the more backstabs you get aswell as the health and your cloak rate It starts of with 25% to 40% faster weapon firing speed 75 health to 165 health and cloak lasting rate from -35% to 60% cloak rate -25%. -25% - -10% - +10% - +25% - 40% for firing speed. 75 to 105 to 125 to 150 to 165 for health. -35% to -20% to normal cloak lasting rate to +15% to +35% to +60%

-25% longer decloaking rate

+35% faster cloaking IN rate

+does not show silhouette when touching an enemy and when hurt aswell as showing no blood

Maybe if you try to backstab a razorback sniper, it sort of stuns the sniper, but the knife makes you slower and gives less health? Idunno, just a thought.

Silent killer: No sound from back stab
Upon a successful backstab: All nearby enemy buildings get sapped
+2 second longer disguise time
Wearer can not cloak for 1 second after a back stab

I reckon that would be a very unique and interesting weapon as it would encourage chain stabs and making sure you don't lose your gain stats by dying

how about

+100% critical hit vs wet players.
+Able to remove Electro Sappers.
+On hit: causes bleed for 6 seconds.
- No random crits.
- Self mark for death when covered in jarate or mad milf.

stats of eyelander heals up to 185 hp and increses invisibility length by 10% each back stab

Fizzle effect

I honestly don't know about the stats or suggestions but I have one,on a backstab,it's not a One hit kill,instead it will shock them for 7 seconds,a whole payload team gets stabbed by it,they're immobile.

1: Spy knife critical hits result in an instant kill
2: Spies place sappers, not remove them
3: The knifes already have no random critical hits
4: Jarate already makes you take mini crits

On Backstab: Does no damage
On Backstab: Disables Target's Primary and Secondary

+ 50% speed while held
- 50% Cloak and Decloak time
- Cannot remove Razorbacks

Could be more of a support weapon, or rather than disabling, A speed -80% on backstab could be cool. Or a reskin whatever

Here are my ideas:
+no effects on wearer when invisible (Fall dmg, Mad milk, Water, Jarate, Bleed, etc)
You still take Damage from bleeding but the enemy cant see you.
+15% faster swing speed

-marked for death, when active
