The sword would not be able to smoothly re-assemble itself, you would end up with a fustercluck of blades sticking to the body and pointing in random directions.

Not to mention a magnetic core string enough to rip the flechettes free and draw them back would attract every metal object within range, burying the user under a pile of random garbage.
