My two cents... no doubt in my mind... purchase the bone cuff for your dominant hand. Why?
Because it's a bold piece, we often talk with our dominant hand, your bone cuff will be beyond striking when your hand is flying around in your daily activities. Buy for your dominant hand! This cuff is meant to be seen!
I agree with
@BigAkoya. When you shake hands with someone or hand them something, you'll use your dominant hand. I’ve worn mine for decades and get compliments on it all the time, despite a bit of patina. I hardly ever get it polished at TCO. The last time was probably 5 years ago. I do need to polish it myself more often, but I’m usually wearing it!
I hadn't thought of it in that way either. I have been percolating about the bone cuff for a bit, even tried it on ( loved it!), but just assumed it would be for my non-dominant hand, as I didn't want to scratch it up, or bang it more than needed. But you make an excellent point. Perfect!- now I have an excuse to go back and try it on the other hand for a bit.
Thanks so much for giving me another perspective on it.
