Martin- What a fascinating project. Photos of the ivory grips and
swords you worked on? I’ve found that Twinkle or Wright’s Silver Polish
and a soft piece of cotton flannel polishes up ivory and bone nicely.
Wet Q-tips with silver polish in a flex shaft will also work nicely
for recesses but one has to be careful of heat and keep things wet.
Makes a mess.
Have fun and make lots of jewelry.
