Razorback. Useless, or not?

Do you equip the Razorback or not? I think it's pretty cool, but I would love to see a gameplay video with it.

Cant you just shoot the sniper 3 times from behind -_- way easier than backstabbing him with him not even dieing, if you shoot fast you'd kill him much quicker/easier.

It's useless.

Why you ask?

Because you can still get backstabbed while wearing it!  It's hillaariiouuusss!

Ive seen one guy with it, it may protect from backstabbs, but it sure dont protect from headshots

but seriously it blows

Tested it out with Kamz because I have yet to gain it. It is useless compared to Jarate and even the SMG.

*You can't apparently tell when it shatters.
*15% speed reduction.
*The stun time on the knife is pathetically short.
*Jarate is just so much more useful.

If I ever get it I'll never use it for more than the first 10 minutes.

Since you can see the Razorback on the Sniper, it would take someone who just got the game, doesn't know about the updates, and has never played spy to fall for it.  Any player with a little experience will know to leave those snipers alone, or just shot 'em in the back

I think you're all missing the point.  Of course experienced spies aren't going to backstab you when you're wearing it.  They'll shoot you instead which gives you a fighting chance to survive.  I fended off at least 7 or 8 spies last night on the second stage of Pipeline in the sniper nest.  A couple tried backstabbing me which didn't work, so they switched to revolver, and I killed them with the machete.  The rest just went straight to revolver, and I killed them with the machete before they could finish me off.

Numenor raises some good points, but I think I can refute them all:

1) You can actually tell when it shatters.  It makes a noise, I think.  It's relatively subtle, but you can tell when it breaks.
2) The speed reduction won't matter much if you're sniping from afar like most sniper rifle snipers do.
3) The stun time is just a bonus.  The point of the Razorback is to alert you that a spy is trying to kill you.
4) Jarate is only more useful if you're moving up with your team.  If you're hanging back to snipe, you'll get more use out of the Razorback.

Now, having said all that, I would like Valve to make two small changes to the Razorback.

1) There needs to be some visual way of knowing that the Razorback broke; or if there already is one, it needs to be more noticable because I can only remember hearing it break, not seeing it break.
2) It would be nice if it gave some sort of HP bonus so it's useful against other classes -- 20 sounds perfect to me.

Abso-fucking-lutely useless.
 
While wearing it you can see a gigantic fucking shield on your back, so spies will walk up, realize that its there, pull their revolver and blow you away. All they need to add is a giant sign and arrow saying "Don't stab me, use your ridiculous revolver instead"

Even if it instantly kills the Spy who stabs him, as well as all other spies near him, it will never be used because it's easily visible.

Its useless,  if you're alone you're dead.  A good spy will revolver you twice before you can switch and can knife/shot once more to finish you off.  Since it slows you down you won't be using it on CP maps, mainly A/D or payload.  A/D it won't be good on (at least good A/D maps) because of scouts, soldiers or demomen jumping at you.  You have nothing to do a little bit of damage to take them out... and you're slower.  Its useful vs. one class and even that class has an easy way around it.  It doesn't replace the SMG or jarate at all,  its a pretty crummy weapon.

What if in addition to how it currently protects against backstabs, it also reduces any attack from behind by 50% (and still breaks after the first use)?
