Currently I have a 4 piece (black titanium) space case. I figured I was getting the best of the best, but due to how it works, and all the holes on top, it just can't do a fine grind the way I like it. Holding it upside down was a makeshift solution at best, and replacing it with a two piece would have made the 4 piece kind of a waste of money (plus the idea that it would still be nice to collect kief). My initial solution was to buy the Magic Flight finishing grinder. Despite not owning a launch box, the finishing grinder seemed like a neat unique grinder to further grind what dropped through my 4 piece. So far, it certainly "works", but the thing is so tiny that it just turns into a hassle and half, leading to many trips from my 4 piece to this dinky cheese grater thing to get amount I need. So I'm back to the drawing board. Aside from just straight up rocking a two piece again, is there any other way to get the grind I want? Seems like there aren't really any 4 piecers out there that really can? Also though about a two piece + a kief box, but I don't really know anything about kief boxes..
