+25 damage to building and robots
-25 damage to humans

Yea something like that except i prefered more than 25% damage but still your idea is good :P

Multitools are frequently shown in spy movies as a medium for disarming bombs, disrupting machinery and creating tools, perhaps this weapon should be more of a tool rather than a stabbing instrument?

Possible Type #1:

+Doubles sapper's speed for 8 seconds after a backstab
-User loses knife after a backstab (Knife could be regenerated through a meter)

Possible Type #2:

+User cloaks for a few seconds after a backstab (Cloak energy is not consumed)
-User loses knife after a backstab (Knife could be regenerated through a meter)

Possible Type #3:

+Increases maximum cloak time (Effects could stack like the eyelander)
-User loses knife after a backstab (Knife could be regenerated through a meter)

Possilbe type 1 sounds ♥♥♥♥♥♥♥ awesome. Overall all your possible types are excellent :)

Hey, that's a nice idea you have on Type #1.

I would make it so that he Spy has a cooldown on backstabs, though - how about 5 seconds of "recharge" between backstabs?

Well Cocoa looks like Jojo likes your idea :D

You do realize you have absolutely no control over any stats, right?

i gotta say this has been the best idea, sticking with the pliers idea is good

@Kira
I'm sure they know, but it doesn't bother me if people want to come up with ideas. Let the creative juices flooooow.

With the weapond in hand you right click the sentry gun to disable it for 3secounds.Cassing the sentry gun to take 2x the normal damage.

+ Destroys sappers (enemy sappers and your, so you can pretend youre the engineer)
+ Faster sapper destroyer when you are near the building you're sapping.
- 8 sec between backstabs
- 50% dmg to players alternative to those above: no backstab from behind, only from the sides or only the left so it is like stopping the blood to the brain
= optional can pretend hitting if disguised as an engineer

this sounds great the spy needs a knife for taking out sentries

A spy without backstabs feels like a pyro without a flamethrower... Goign with hitting the enemy sentry, the only way to uncloak (Thinking of a reason why you would lol) would be from shooting your revolver.
I'm also thinking increased sapper power with each backstab

+100% Damage vs Buildings
+100% Damage vs Enemy and Friendly Sappers
+Do not lose disguise when you attack a Sapper while disguised as an Engineer
+Increased Sapper power with each removed Sapper or destroyed building
+10% Sapper Damage
-Disables Backstab
-Lose disguise when placing sappers
-50% Damage vs Player

+35% damage to players
-45% swing recovery
