i have a sharpstone 4 piece grinder and i really havent used it much...id probably say a max of 7 grams of dank was grinded... i have a feeling this grinder is gonna collect a whole lot of keif...just wait till i grind an o through this thing
Also, don't assume more is better, the finer the screen the better the kief. A friend has a cheapo grinder with a huge screen so obviously he gets all kinda trash in there along with his kief. I use a 120 wikka and even think they're 100 screens let in too much...
i have a sharpestone windmill style 4 piece taht i thought the same thing about...i thought maybe the sharpness of the blades maybe had something to do with it
