The key to this whole thread is flat & sharp! Meaning surfaces and corners... The end result, whether shiny or dull, is going to look either great, or like sh**t if the edges are round and the flats wavy???
If you look on the internet, there are degrees of finish documented that go from high polish to flat. I think the info stating 220 W/D or there about is probably as close as you can get by hand, and the final prep, whether it be a charged wheel, tumbling, or blasting is a matter of choice and trial and error...
.... Lot'sa effort, and most certainly a quest.... best to all, til....lat'r.....GT
