Being able to hold knives the other way
Knives are fun, and I hope they get added into the buy menu again, but besides that, I think you should be able to hold the knife the other way around. This would make it more interactable and interesting to use, as it opens up more options for attacking people. The way I see this working the best is it depending on which way your hand is when you grab it out of the holster, pertaining to how you grip a real knife. It should probably not matter how you're holding it when you reholster it, just for QoL.
