I just tried it. It was pretty easy to make the sword itself. Rather then think of making a sword though, I just made two psi/chi balls and put them together then stretched it into a long club. Kind of like a narrow baseball bat. After that I made the edge and hand guard. It wasn't that hard and only required enough concentration to make the psi/chi balls.
A little side-note: I said "psi/chi" balls because some people may be unsure of which is which with psi or chi. Psi, from what I understand is brain energy. Chi, from what I understand, is body energy. I think, perhaps, making a sword would involve both since the base (of mine) was made from chi while the shape was given by psi. I also think I need to study both chi energy and psi energy more then I have. :)
