Remove the odd hat from hat crates

[Mouse]

Its rare to get the odd hat and if you miss your throw it comes back and cuts off your arm. I'd say its fine.
By the way the only way it can decap people is if you already cut off all their other limbs I believe. At least thats how it worked for me when I got it months ago.
If people are specifically fishing for it as you say then those people need to get an admin talking to just like anyone else abusing game mechanics.

If you miss your throw it damages you, but it doesn't delimb.  It decapitates (or at least has an extremely high chance to) if it hits someone in crit.
