Psylocke's Psychic Weapons

Hello guys,



I read some new x-men comics 2 weeks ago and I noticed Psylocke's new skintight costume with the long red-purple sash.



I realized that Psylocke conjured not only her usual psychic knife or katana, but also some other weapons:



- psychic crossbow

- psychic bow & arrow

- psychic flail



First of all, I'm a fan of Psylocke but I never really understood her psi-weapons, even her original psi-knife. Please kindly explain to me,



How does Psylocke produce psi-knife and psi-katana?

How does Psylocke produce her other psy-weapons psychically?

Did she get a power-upgrade to produce these weapons?

Are Jean/Emma/Rachel capable of producing their own psychic weapons?

Is Psylocke capable of creating any psychic tangible-things?

Is Psylocke's psychic weapon actually a manifestation of her energy?



Thanks!
