By the way, Jens I always love your pictures - and am insanely jealous.

Battara; Great information about Sulfur changing ivory yellow.
I know for a fact, unfortunately, that rubber bands have a lot of sulfur in them, and I assume all rubber products also has sulfur in them. The rubber bands were stored in a box with some of my old Silver coins and the coins turn black
Question, Battara, on this dagger as well as others daggers/knives that I have with ivory handles I use Renaissance Wax on them, will that protect them from the effects of ambient sulfur?
