It should do 20 Damage and Bleeding for 6 sec

how about instakill

Pros:
On Backstab: attacker bleeds for 9 seconds and attacker cant use melee weapon for 7 seconds and decreases attackers firing speed and damage for 8 seconds
+5% bleed damage

Cons:
Can still get back stab
-10% damage penalty on all weapons
+10% damage taken from all resources on wearer

The bleed effect does about 40 dmg over a span of 5 seconds, so 12 seconds would do almost 120, making it so low health spies and Conniver spies will most certainly die, it would be nice, as pro spies would see it as bait for death, and choose to ignore the sniper, or just shoot at him, definantly a more unique approach at a M.A.D tecnique for snipers to use against spies. (M.A.D = Mutually Assured Destruction)

+30 bullet resistance
backstabber can't backstab until death
or somethin

Short and balanced stats:

Pros:

Prevents one backstab
Backstabs cause the attacker to bleed for 6 seconds

Cons:

-15% Speed on wearer. (You have a weighted metal trap on your back...)
-15% Sniper charge rate. (Trying to balance yourself out, since you have a heavy, metal trap messing with your posisioning)

pros:
6 sec of bleed on backstabber.

con:
no secondary weapon.
no backstab immunaty (you will still die)

Pros:
Once backstabbed, enemy takes 25 damage,
is stunned for 5 second,
and bleeds for 5 seconds.
backstabber can't backstab for 10 seconds, due to almost having hand amputated,
and backstabber is less acurate, due to having hand almost amputated,
and If backstabber is using spycicle, it shatters.

Cons:
Once backstabbed you loose half your health,
trap cannot be used again ,because its on your back and you cant open it up,
you take more fire damage, because you have metal on your back,
you move slower,
trap can randomly be activated when shot.
when reloading bow, chance you will trigger trap and be affected,
you are really slow, due to HUGE trap on back,
and no secondary because you would chop your arm off trying to take it off your back.

These stats are based upon logic and balance. more bad stuff because it is VERY powerful and heavy.

Or here are some alternatives...

Pros:
backstabber has no knife, because it is stuck in trap,
backstabber is suprised and cannot attack for 3 seconds,

Cons:
If backstabber is using spycicle, his knife will will soon regenerate,
you are slower,
its a one time use,
and no secondary.

razrbek reskin!!1!

When an enemy hits you in the back with a melee weapon, you take 50% of that damage and they take ~50 damage, get bleed for 5 seconds, and cannot swing their melee for the duration that they have bleed (so if a scout with the basher/cleaver/wrap assassin comes along, they can extend the bleed time and disable the attacker) a good teamwork item
Also, the activation removes the trap, similar to the razorback.
Does not block backstabs.

Pros: On Backstab: makes a masive chomp sound to indicate spies and takes half health of attacker while doing bleed damage for 20 seconds and rearms it self after 10 seconds
Cons:
-10% speed on wearer
Will be broken while it rearms it self

on backstab attacker lost 50 health
bleed for 6 seconds
lose your trap when backstab
-10 speed on wearer

What if on backstab attacker will die instantly but Sniper will die too.

This should soup-rice alot of people.

+When back-attacked by a melee weapon, enemy loses all ammo for primary weapon.
+If attack was crit, reflect back to attacker.
+Right-Click to drop and set a Bear Trap. Trap activates when enemy makes contact.
+Upon enemy contact, trap emits a loud, metal snap sound and immobilizes trappie for 3 seconds, and inflicts bleed for 7.

-Trap has 75HP and can be destroyed.
-20% Movement speed when available.
-30% Fire vulnerability.
