Where and how would be the safest places to take a sword cut? (It doesnt have to be that deep but where would be the safest places so as to be able to keep fighting?)

There isn’t one. With knives you can “safely” take a couple strikes to some areas of the forearm, but, that doesn’t hold up for a sword. So the safest place to take a sword strike is anywhere you’re not standing. Failing that, taking a blow to the shield, or to heavy armor, or parrying with your own weapon is about as good as it gets. Taking a sword strike to exposed tissue is almost always going to run the risk of a crippling, or lethal injury. You can get lucky, and suffer a superficial injury nearly anywhere, but it will never be “safe.”
