High SPM means nothing, The knife is a last resort and it should be used as such.
with over 1k kills with the knife i'm willing to bet countless teammates of yours have been killed because you chose to knife instead of shoot. Weither because you allowed them to be shot or you died before you could rez them.
90% of the time the knife is not a viable weapon, the 10% of the time it is. Is when it's a single sniper on his own lying on a rock, or when your our of ammo and have nothing to loose. Now iI'm not gonna say stop playing for fun and running about knifing people, im simply saying it how it is.
