Is it possible?

[-Ignorak-]

I was thinking of making a realism mod for personal use, maybe even realease it, i've started implimenting basic things i found in the guide of useful scripts, now im wondering, seeming i saw this on the suggestions/discussions about swords unable to simply go through each other like they normally do and instead, both swords are unable to pass each other.

It'd be something to do with collision events/meshes would it?

If so would it even be possible to some degree
