Media blasting?

[Rottie blades]

Hello everyone. I just picked up my HF media blaster for blasting knives before acid stonewashing as well as doing the occasional matte finish on some stainless steel. What media do I need? What's the best universal media for the tasks mentioned above because I don't want to have to switch media out everytimei do another task. Any help is appreciated!

Try garnet sand or even aluminum oxide for a more premium blasting material.
