I didn't mean a built-in timer, Leaf, and certainly not coincidence. The fact that the blade would dissolve eventually was built in, I think, but being exposed to the light certainly sped the process up - like iron rusts faster in water than in air.

Zil, I think you're on to something bringing the dualism of wraithworld and "light" world into the picture. Maybe the way the knife was to 'wraithify' its victim was by fading back into the wraithworld after it had pierced them and taking the victim with it?
