I use a number 80 glass bead. For variance in shade and finish look you can mix ceramic and glass, sand and ceramic, sand and glass, sand, glass and ceramic and play with various recipes if you will but when you start doing that you need to make good notes on how you did it to easily repeat the process so things look the same for you as you make more or have to retouch those already made up and sold or passed on to family.
Whatever the titanium is normally blasted or hand rubbed to some level of brushed finish. I have not seen shiny per say although some of them have a more glossy look to them. You can blast the ti first, tumble it in a rock tumbler to give it a finish that way or you can after blasting it all over simply lay it flat on a surface that won't scratch it and simply grab a green Scotchbrite pad and start rubbing one direction only in straight lines and just rub the side you want exposed down until it reaches a finish level or look you like. If the piece is all scratched up you may need to put some equipment and muscle into it first to clean those up and then blast, then rub but one way or the other you can come up with a good look.
If you don't like it simply blast it over again and it can be left that way. I like ti. Its not as hard and won't wear quite as well as stainless but it sticks in place better than stainless, is less weight by about 2/3rds usually and overall the benefits of it are pretty good. It indents easier than hardened steel but otherwise it should wear about the same for most other uses.
