what advantage does this have over other knives? why would I use your knife over stock? These are the questions you should be asking yourself when deciding on a weapons stats; never once as a spy had I felt as if I needed to switch to my knife faster. Also, the situation where I would like +50% stabbing rate is very very rare. As it stands, this weapon is a straight downgrade from stock.

2/10 think through your stats before posting them.

I'd say most of that is good, but a bit more like
+Each succesful backstab charges rage, when activated you get +10% speed, +50% faster weapon switch, +40% faster weapon swing
-Contact with enemy removes your disguise
-2.5 seconds of cloak time
Just that simple. The reason the rage would be useful is if there is a large group of enemies, you can do stuff like backstab an engineer sap his sentry and backstab everyone else in front of you (if you are good enought to carry out this plan, this will be usefull) However sice bumping an enemy loses your disguise and you have less cloak, it will be harder to actually stealthily infiltrate this nest.

+25% speed recovery from backstabs (the next time you can swing your knife into another back)
-25% damage
silent killer
can headshot
no random crits

after 3 backstabs you can throw the knife to get another backstab but if you miss you must collect it

maybe this

pros:
-on backstab:gains a stack of 'death'
-alt fire: consumes 3 stacks of death to get instantly behind a target at any range

cons:
-50% less cloack duration on wearer

My idea:
Pros:
+20% damage from non-backstabs
Silent Killer
Cons:
20% Slower Weapon Switch
10% Slower Swing rate
-------------------------------------------------------------------------------------------------------------
Alt Fire: Throw knife. Knife must be collected from wherever it lands afterwards.
Knife throws that hit enemies in the head deal damage=Backstab.
Knife projectile flies in an ark close to that of Jarate, so people can't just throw knives from across the map at people to insta-kill them.

+20 demage
on fire -
mini crits ( not to op)
-30 life
- 2 clock seconds or something like that

i like the idea of make problems to pyro's
to easy to play this class
only w + m1 or m2
i think... the spy....the class need something like that

What would happen when you lose your knife and you have no ammo? would the spy have his fists?

Very very true. On a weapon, I posted stats, which I, and another person later found OP. We had a long discussion on it, and i think the stats turned out pretty well, but too basic as well. Check out the Crescendo, on the Battle of the Bands set. I am trying to think of a new mechanic for it. Oh, that also brings up the main subject for spy knives: new mechanics! Please!

(I posted all of this on the other stat discussion too.)
How to make good stats for a spy knife (and any other weapon):
1. It helps to look at the weapons name. The name is the base of all of my stats, and i add cool affects that go with the name as well. Check out "Crescendo" to see what I mean.

2. New mechanics! DO NOT, and I repeat, DO NOT make stats if they are just going to simply change barely from the stock. You have to have a weapon that changes the gameplay experience all together, not just some weapon that has stats.

3.(Optional) Teaching weapons: Teaching weapons are weapons that teach you skills and purposes for that class. For example: The Diamond back teaches you what to do as a spy, as far as backstabbing and sapping goes. And then it rewards you with crits! The Rocket/Stickey Jumper help you learn jumping techniques!

4.The stats have to be balanced. Enough said.

With all of that being told, I hope all of you guys choose wisely upon this.

Here are my stats for this cool knife:

Pro's:
On backstab, you gain full health.

Con's:
Facestabs do no damage.
Sappers don't disable sentries, they make their damage -60% and they take 30% more damage.

On each backstab, sappers work 10% faster. (Example: 1 backstab= +10% sapper speed,
2 backstabs = 20% sapper speed, etc.)
On each attempted facestab, sappers work 10% slower. (Example: 1 attempted facestab = -10% sapper speed, 2 attempted facestabs = -20% sapper speed, etc.)

Do you see the new mechanic I tried to put in there?

I tried as hard as i could to make stats and a new mechanic in 3 minutes along the lines of what I just said, but mind you, this stat set will be edited.

There should be a mechanic where on backstab +1 crit on hit.Anyone think this is good?

It'd regen after a short time, as thrown weapons in games are wont to do.

this isnt call of duty. get out.

+Silent Killer
+On Backstab: gain 15 health
+Razorback delay immunity
+full crits on primary weapon while sapping a building
-On miss: hit yourself for 35 damage and bleed for 5 seconds.
-On Hit other than Backstab: lose 15 health

encourages talented spies to be conservative when attempting a stab. encourages prominent use of sapping ability.
razorback delay immunity is just a little fun gimmick like double kills on the machina or the fall damage effect on mantreads.

-5% health
-15% damage
cannot 1 kill people with backstab
can only backstab one people in 1 health

when backstab: stuns your enemy for 10 seconds and bleed for 5 seconds

when someone get stunned by this knife: people can only use meele or shotgun to kill them
100% critical hits when someone get backstabbed by this knife in 8 seconds

i mean: can only backstab the same guy 1 time in 1 health. sorry my bad
