TK blasts are hitting people with objects wrapped in your mind stuff. It doesn't specify a minimum size, though, so some allow any speck of dust to be the object, or maximum size, although I'd houserules limited to your basic TK weight... It also doesn't say if your mind stuff is visible or not.
KB for TK doesn't make the purely cosmetic shape that the other energies do, just lets you wield it like melee instead of the normal blast. So, you could ask GM if your mindstuff can be visible and 'saber shaped, concealing that you're just smacking them with a rolled up newspaper or granola crumbles. Or use any sword or weapon that you wield as your blast, not as whatever it is.
For a light saber look naturally, air-electric, or maybe a 3p light element, could work better.
Doesn't EA gives up up all the utility wild talents, including even the Basic? Doesn't seem very Jedi like.
