Butterfly Knife Traitor Item

[Man of San]

I'm a bit leery of so clearly a reference to TF2 in both form and function. But I do like the idea of the idea. I'm not sure how to make it suitably unique here though.

The one comment I do have on the base idea is that a 5 second stun on a back hit is too strong, unless it has caveats. Like perhaps it shouldn't work on people who are combat staggered or if they have already been stabbed by you in the last few seconds. Maybe a shorter weaken or disorient effect would be better. Because otherwise you could pretty easily keep stabbing them with the stun effect.

Changed it up a bit again, does this seem better?
