Best knife kill I have ever seen was Pavel from BCAC years ago. If some of the oldschool BCAC guys see this they will probably remember. Anyways Jer was driving his open top sidekick around the field, him driving and three others in side. Pavel jumps out and runs up to the sidekick and runs around the vehicle knifing everyone inside of it before running off.
People who know Pavel know he is straight up ninja.
