Okay, armour created from Ivory is not too far-fetched - lacquered wood and boiled leather both make reasonable armours. I could see alchemists involved in the preparation of the substance but not in the actual construction of the armour.
Apart from Moons comment on Ivory being bone (its not, similar, but different) his comments are spot on.
Hmm, if the outer edges are instead sharpened, this weapon would gain more usability, being usable somewhat conventionally as a normal, if heavy, sword. This is especially important since the mechanical complexity of the blade could fail after a hard parry or the like. Fully open, the blades would cover a wide area and might even serve as a weapon-breaker.
Odd, flamboyant with definite downsides, it still has value. Go to Comment
