I am currently experimenting the luxeon blades in conjunction with a "slider" within the blade for extension / retraction effects. I don't think it would make a good duel blade, but I do believe it could make a nice show blade.

here's what I came up so far:

I'm open to all comments/suggestions on the matter.

The main idea would be to have a small magnet in the base and the tip of the blade. I still have to figure out how to properly release the bearing.

I don't think this should be used in duel for 2 reason
1- the bearing might get loose of the magnet upon impact and "shut down" the blade.

2- if the tip goes off, you have a metal bearing flying trough the air. I think this is uterly dangerous.

otherwise, I think this isn't all that bad.

what do you think??
