If you're a pure or near-pure caster, and the distortion weapon in question can butcher, just leave it in place. Trying to train fighting with it will be annoying, but it isn't necessarily crippling. Distortion is actually a very high-damage brand for a fast weapon, although uncontrolled blinking of enemies makes it hard to maintain a defensive corridor. Eventually, you will be strong enough to survive a trip to the Abyss, and at this point you can discard it.
If the distortion weapon is absolutely unacceptable for whatever reason, get to a completely-cleared level and unwield it while hoping for the best. The chance of banishment is actually fairly slim, but there's also the possibility of up to nearly 50hp worth of damage, random forced teleportation within the level, and fairly long-lasting confusion. Or you could get no negative effect whatsoever. Grab a good stack of food and whatever teleportation scrolls and speed potions you've accumulated up to this point, and even a fairly low-level character can possibly survive an unlucky Abyssing.
