Hmm... true, he should be able to do those slashing / cutting techniques with any other sword or bladed weapon besides his nodachi. Therefore the point will be to disarm him from any sharp bladed weapon at all, not specifically targetting his nodachi only.

Also, not any long range fighters (e.g. snipers, etc) could work, because we have seen how Law countered incoming bullets in his Room. Unless the bullet is so fast that Law could not see / detect.
