Pretty much the title of my post says it. But it would be great if we can turn off our effects on weapon upgrades. Sometimes I would love to use my knives in their original state before I upgraded them. I mean technically we bought that style too but lose the option to use it. In game the only person that sees knife effects is the one holding the knife (or dead teammates) players that own the weapons should be able to remove what they might find distracting. Just my thoughts.
