• Blocks a single spy backstab

The Razorback is one of the three new weapons introduced with the sniper vs. spy update. The weapon is being unlocked once you complete 17 sniper achievements thus completing the "Sniper Milestone 3".

The Razorback works like a shield for the back of the sniper. If an enemy spy tries to backstab you, he will be stunned for 2 seconds and won't be able to attack with his knife. When hit, the razorback breaks into pieces and you have to get back to your resupply locker to get a new one.
