I know the brushed option is there, but I was really hoping for a true Ti buckle. Someone on the Paneristi site is making them, but he's looking for $150/buckle, which I think is rather high.
I have an aluminum oxide blaster at my office with 27um and 50um particles, but I'm quite certain that it wouldn't stay that way. Any rub/scuff will leave a shiny spot.
Maybe if we all requested a Ti buckle one of the dealers would make them. Titanium is cheap these days.
