[General] What are the advantages and disadvantages of having a weapon physically fused to your body?

In several works of fiction characters will often have a weapon fused to their bodies, swords to arms, guns to legs, bladed legs etc... So for exanple would someone with a blade for an arm (below the elbow) facing someone of equal skill but with a traditional sword, would he be at an advantage as the blade is effectively an extension of his arm or would he face an issue with flexibility because of lack of a wrist?

edit: only for combat situations, obviously you cant just bring your sword arm to school.

Edit 2: how does having a sword arm become an advantage? Giving it a wrist?

I'll go with the sword arm as an example.

There would definitely be an issue with flexibility of the wrist. A lot of sword fighting techniques require you to twist the blade around. That becomes difficult  when it's fused to wour arm. You also lose the ability to use that body part for anything other than fighting. You may be able to kill someone with a punch, but you lose the ability to do anything that requires two hands. Sure, it's a convenient way to carry your weapon around, but you'll likely be band from any place where weapons are prohibited.
