if you have the resources you might as well, at the very least kill enemies near save rooms. dont want to have to have to worry about getting hit in a area youll be constantly returning to. shoot a zombie in the head enough to drop them then knife them while their down. make sure they dont move any more when you hit them (give it a few seconds before hitting them one more time), sometimes they like to fake it. provided you arnt getting grabed constantly there should be enough knife "strength" to do so.
